14 Square Examples in Real Life – StudiousGuy

A square is a quadrilateral geometric shape that consists of four equal sides and four equal angles. The area of a square can be obtained by evaluating the numerical product of its two sides. The perimeter of the square is four times the magnitude of the side.

1. The sum of all the angles of a quadrilateral is equal to 360°, and all the angles of a square are equal in magnitude; therefore, the angles formed between the two adjacent sides of a square is equal to 90°.

2. The opposite sides of a square are parallel to each other.

3. The two diagonals formed by joining the opposite corners of a square are equal in length and have the value √2 times the magnitude of the side of the square.

4. The diagonals bisect each other at an angle of 90°.

1. Floor and Wall Tiles

Most of the tiles used in constructing and decorating home walls and floors are square-shaped. Hence, the tiles are one of the prominent examples of square-shaped objects used in everyday life.

Everyone has a stack of napkins placed on the top of the dining table. A napkin is a square-shaped piece of paper or a cloth that is used to wipe the mouth, hands, or objects. Hence, it is yet another example of square-shaped objects used in daily life.

The chessboard is one of the best examples of the square-shaped objects used in everyday life. Not only the outer boundary of the chessboard is shaped like a square, but it also contains 64 small square boxes on the inside.

A stamp is a small piece of paper that is affixed on the front side of the envelope containing the letter before posting it. Most of the stamps are square in shape.

A cushion is a bag of fabric that is stuffed with cotton, fur, wool, or beans. The cushions used to decorate the living room are generally square in shape.

In real life, the square geometric shape can be observed easily by looking at the front face of a cubical desk clock. Some of the wall clocks are also square-shaped.

A loaf of bread is generally cuboidal in shape; however, if you pick one thin slice of the bread you can easily identify its square shape.

The shape of the cheese slices is square. This is because it is easier for the manufacturing industries to wrap a square slice instead of wrapping a round slice.

Most of the windows installed in homes are square in shape. In some cases, not just the outer frame but the glass inside the grilles is also square-shaped.

If you clearly observe the front face of the chocolate cube, all four sides are equal, and the opposite sides are parallel to each other. Hence, the cube taken out of a bar of chocolate is yet another example of the square-shaped objects seen in everyday life.

Photo frames come in a variety of shapes. One of the most popular shapes of a photo frame is a square.

Some of the biscuits are baked in the shape of a quadrilateral that has all sides equal, i.e., in the shape of a square. So, next time while eating a biscuit don’t forget to get yourself reminded of the square geometric shape and its properties.

A craft paper is a colourful and textured piece of paper that is used to model a number of paper artefacts. It is generally square in shape.

14. Bedsheet

One of the most commonly used objects in daily life that is square in shape is a bedsheet. It thoroughly covers the mattress and protects it from dust and stains.

A square is defined as “a plane figure with four equal sides and four right (90°) angles.“¹ 

The world is filled with geometric shapes, and geometric forms can be found everywhere. Most things are made up of geometric shapes, whether two-dimensional (2D) or three-dimensional (3D).² Among the most commonly seen forms around us are squares. You will be surprised by how fascinating and valuable a square can be when you discover more about it. They work well for construction, decoration, and the creation of 3D shapes. The following are a few examples of squares being used in real life:²,³

• Tiles

Most tiles used in building and decorating interior walls and floors are square in shape and range in size from small to large. The convenience of working with square tiles is an added benefit. ⁴

• Chess

A chessboard is one of the best examples of a square-shaped object in daily life. The chessboard’s interior is made up of 64 tiny square boxes in addition to its square-shaped outer border.

• Toasts, Sandwich, Waffles, Brownies, and Chocolates

These popular snacks can be clearly seen to have equal sides on all four, with the opposite sides running parallel to one another. Therefore, these foods can serve as a wonderful illustration of the square objects encountered in daily life.

• Photos and Picture Frames

A square is a perfectly balanced shape with equally long sides. As a result, neither the horizontal nor vertical direction is highlighted. One of the main reasons why photographs and frames are typically square is that it makes the object appear more esthetically pleasing.⁵

• Windows

The vast majority of windows installed in homes have a square shape. It is possible for the inner glass of the grilles to be square as well, not just the outer frame. This is because joining two pieces of wood or aluminum with straight cuts is simpler and faster when producing the components in large quantities. Additionally, cutting the glass into square shapes is simpler too.

• Construction, Decoration, and Art

Squares are easy to make, cut, or build from everyday materials.  A square is one of the few regular polygons that can tessellate a surface. This makes a square very practical for construction, decoration, and artistic creation.⁶

What is living space

Living space - the sum of square meters of all premises suitable for life (Photo: Meruyert Gonullu/Pexels)

Living area - the total square meters of all premises of the property suitable for life. The definition is specified in the order of the Ministry of Zemstroy of Russia No. 37 of August 4, 1998. In practical terms, this is the total area of ​​living rooms. The living area is fixed in the documents for the object, but may change due to redevelopment or reconstruction.

The indicator is taken into account when:

• calculation of utility bills in the absence of meters;
• the allocation of meters to the property of beneficiaries, the determination of social payments for housing;
• land tax calculation;
• determining shares in the common property of an apartment building and the amount of subsidies;
• conclusion of contracts related to real estate;
• examination of the living conditions of minors by guardianship authorities.

It is often mistakenly believed that living space affects the amount of property tax. In fact, this tax is calculated according to the size of the total area of ​​the object. nine0003

What is included in the living area of ​​the apartment

Living space includes only rooms - bedrooms, children's rooms, living rooms. Dressing rooms and pantries are non-residential space and are not taken into account in the calculations; stairs and heating stoves in private houses are residential meters. The kitchen, corridor, balcony and bathroom are also not included in the living area. Some elements of the property are considered individually: for example, arches and niches can be included in the living space if they reach at least 2 m in height. nine0003

Total and living area of ​​the apartment - what is the difference

Living area - the sum of the areas of living rooms [1]. And the total footage of the apartment takes into account all the premises, including utility rooms, but with the exception of balconies, terraces and loggias [2]. There is also a third indicator - the area of ​​​​the apartment. It takes into account all the premises that the owner can use. Some of them count with a certain coefficient:

• balconies (terraces, verandas) - 0.3;
• loggias - 0.5;
nine0009 pantries, verandas - 1. 0.

How to determine the living area of ​​an apartment

Living space can be measured manually or order a detailed extract from the BTI (Photo: Tima Miroshnichenko/Pexels)

Information about the areas of all rooms is indicated in the technical passport of the room. For complete information, you can order a detailed extract from the BTI. nine0003

Social norm of living space per person in 2022

Living space norm per person — 33 sq. m (Photo: Karolina Grabowska/Pexels)

The Housing Code of the Russian Federation contains the basic provisions on living space footage. Standards for the provision of living space per person - 33 sq. m, for two - 42 sq. m. If the family consists of three or more people, each of them is entitled to a minimum of 18 square meters. m. Regions and municipalities can set their own standards - but no less than federal ones. For example, in the Chechen Republic there is a norm for the provision of housing for a family of two people related by kinship (parents and children), which is 50 square meters. m.

In addition, there is a sanitary provision for housing. In Russia, this 6 sq. m per person, the indicator is used when calculating the area of ​​​​apartments and rooms for temporary residence: for example, to accommodate people in a flexible fund during the overhaul of a house or in a hostel [3].

Expert comment

Nadezhda Korkka , managing partner of Metrium, member of the CBRE partner network:

— How does the footage of real estate affect payments for common house needs?

— If the house is equipped with common house meters for cold, hot water, sewage, electricity and gas, the area of ​​the apartment is taken into account when calculating payments for common house needs.

How to calculate living space in a studio apartment when the kitchen is combined with the living room? nine0024

— There is no such thing as a studio in the current regulatory documents (including building codes and regulations), it is considered a one-room apartment. The living area of ​​the studio is calculated as the difference between the total footage and the area of ​​the bathroom.

— What residential areas are not taxed? Are there deductions for an apartment, room, house?

— When calculating property tax, a deduction of 50 sq. m for a country house, 20 sq. m - for an apartment, 10 sq. m - for the room. This is the reason for the decision of some developers to include in their projects studios with an area of ​​up to 19.9 sq. m. In addition, if the apartment is up to 35 square meters. m lives a family with three or more minor children, this is the basis for tax exemption.

— What should I do if the DDU agreement does not provide for a decrease or increase in the area of ​​the finished apartment, but it does not correspond to the one declared when it was signed?

— The law on shared construction contains a rule that there can be a deviation of no more than 5% between the design and actual area. If the share agreement does not specify the procedure for recalculating the cost of an apartment, then the results of the measurement can be challenged in court. In addition, if there is a significant discrepancy in the area, the DDU can be terminated by court. nine0003

Objects | JavaScript Camp

Objects are like a closet📦 for things, designed to store 📦 and transport other types of data. JavaScript is designed around a simple paradigm. The concept is based on simple objects. An object is a set of properties, and each property consists of a name (key) and a value associated with that name. The property value can be a function⚙️ which can be called an object method or any other type.

In this article, we will look at the most basic properties of JavaScript objects, creating🏗️ and changing, listing properties.

An object in JavaScript is just an associative array or, in other words, a "hash". It stores any "key : value" matches and has several standard methods.

Objects in JavaScript, like objects in real life (person👨, bus, building, etc.) have several named (key🗝️) parameters (age, name, hair color, status) with specific values ​​(15, John, black, 'true') ✅ :

 let obj = { 
 age: 15, 
 name: 'John', 
 color: 'black', 
 student: true 
 } 
 

An object method in JavaScript is just a function that is added to an associative array.

function learnJavaScript() { let obj = { // properties : values age: 15 name: 'John', // method : function say: () => 'Hello!' } return obj.say() }

 
 function learnJavaScript() { 
 
 let obj = { 
 
 // properties : values ​​
 
 age: 15, 
 
 name: 'John', 
 
 // method : function 
 
 say: () => 'Hello!' 
 
} 
 
 Return Obj.say () 
 
}

Creation it with property names (

access keys ). Inside the cabinet📦 drawers🧰 are data (specific information) and there may even be smaller objects, by analogy with things. By key the desired box🧰 is easy to find, delete or add (write) a new value into it.

These are two 2️⃣ options for creating🏗️ an empty object:

 // equivalent entries 
 let obj = {} 
 let person = new Object() 
 

The second option is very rarely used in practice.

Extended creation0132 key : value,

...} and create🏗️ complex objects:

function learnJavaScript() { const obj = { age: 15 name: 'John', color: 'black' passport: { serial: 5721, number: 258963, date: '10/27/2015' }, student: true } return obj.passport.date }

 
 function learnJavaScript() { 
 
 const obj = { 
 
 age: 15, 
 
 name: 'John', 
 
 color: 'black', 
 
 passport: { 
 
 Serial: 5721, 
 
 Number: 258963, 
 
 Date: '27 . 10.2015 '
 
}, 
 
 Student: True 
 
} 
 
 RETURN OBJ.PASSPORT.DATE 
} 
 
 
} 
 9000} 
 
 The created 🏗️ object contains five properties with specific values, one of which is passport data, which is a built-in object. Pay attention to how the far properties or methods of the object are accessed. Try to get your passport number back. 
 
 Adding properties 
 
 
 
 There are two 2️⃣ syntaxes for adding properties to an object. 1️⃣ The first is a dot, the second is square brackets: 
 
 // equivalent notation 
 obj.age = 15 
 obj['age'] = 15 
 
 
 function learnJavaScript() { let obj = { name: 'John' } obj.age = 15 return obj.age } 
 
 
 function learnJavaScript() { 
 
 let obj = { 
 
 name: 'John' 
 
 } 
 
 obj.age = 15 
 
 return obj.age 
 
 } 
 
 
 Loading... 
 
 Square brackets are mainly used when  property name  (properties) is in  variable  🔔 : 
 
 let nameProp = 'age' 
 obj[nameProp] = 15 
 here through variable 🔔  nameProp  set the property name  "age"  , which is the key in the associative array, which contains  value 15  . 
 
 function learnJavaScript() { let obj = { name: 'John' } let nameProp = 'age' obj[nameProp] = 15 return obj.age } nine0003 
 
 Function Learnjavascript () {
 
 Let’s = {
 
 NAME: 'John' 
 
} 
 Let Nameprop = 'Age' 
 
 OBJ [Nameproprop] = 15 
 
 returned 
 
 Loading... 
 
 Property access 
 
 
 
 Property is accessed by accessing it let obj = {} // object is empty obj.age = 17 // equivalent to obj['age']=17 or just obj={age:17} let result1 = obj.age // Option 1 let result2 = obj['age'] // Option 2 return result1 + ' or ' + result2 } nine0003 
 
 function learnJavaScript() { 
 
 let obj = {} // empty object 
 
 obj.age = 17 // equivalent to obj['age']=17 or immediately obj={age:17} 
 
 let result1 = obj.age // Option 1 
 
 let result2 = obj['age'] // Option 2 
 
 return result1 + ' or ' + result2 
 
 } 
 
 
 Loading. .. 
 
 If object  doesn't have such a property is  , then the result will be  'undefined'  . Check it out in your browser console. nine0003 
 let obj = {} 
 obj.nokey 
 
 
 
 
 There will be no error🙅‍♂️ when accessing a non-existent property, it will just return the special value  undefined  . If there is no key word 🗝️  return  inside the function⚙️, the value  undefined  will also be returned - the absence of something. 
 
 Deleting properties Try to remove the passport number from the previous example: 
 
 Create an object from the previous example in the console. 
 
 const obj = { 
 age: 15, 
 name: 'John', 
 color: 'black', 
 passport: { 
 serial: 5721, 
 number: 258963, 
 date: '10/27/2015' 
 }, 
 student: true 
 } 
 
 
 And now delete the nested object  passport  
 
 delete obj.passport 
 
 
 Now, if we refer to it, we will get  undefined  
 objport 
 as a result1 
 
 
 
 Object methods 
 
 For example, create🏗️ object  sport  immediately with method  run  : 
 
 function learnJavaScript() { let sport = { run: n => 'John' + ' ran ' + n + ' meters!' } return sport. run(300) } 
 
 
 function learnJavaScript() { 
 
 let sport = { 
 
 run: n => 'John' + ' ran ' + n + ' meters!' nine0003 
 } 
 
 return sport.run(300) 
 
 } 
 
 
 Loading... 
 
 Adding a method .} 
 property  sport.run  . 
 
 function learnJavaScript() { let sport = {} sport.run = n => 'The athlete ran ' + n + ' meters and it was ' + 'Nikita' return sport.run(350) } 
 
 
 function learnJavaScript() { 
 
 let sport = {} 
 
 sport.run = n => 'The athlete ran ' + n + ' meters and it was ' + 'Nikita' 
 
 return sport.run(350) 
 
 } 
 
 
 Loading. .. 
 
 This is not about classes, creating🏗️ instances, and the like. Simple - you can add a new method to any object at any time or remove an existing one. 
 
 Enumerating object properties 
 
 
 
 To enumerate all object properties, a special construction type is used0132 for . . in  : 
 
 for(let key in obj) { 
 // key - property name 
 // obj[key] - property value 
 ... 
 } 
 
 
 For example 👇 : 
 
 function learnJavaScript () { let result = '' const obj = { age: 15 b: 'true', color: 'red' } for (let key in obj) { result += key + ': ' + obj[key] + ' ' } return result } 
 
 
 function learnJavaScript() { 
 
 let result = '' 
 
 const obj = { 
 
 age: 15, 
 
 b: 'true', 
 
 color: 'red' 
 
 } ' 
 
 } 
 
 return result 
 
 } 
 
 
 Loading... 
 
 And to be honest, almost any variable 🔔 is a mini-object in the JavaScript environment. So don't be afraid to use them. 
 
 React Native0003 
 Try displaying other data, such as the passport series. 
 
 problems function obj() 
  
  let x = 10  
  
 Object stores matches: 
 
 
 first name : last name 
 
 Iterating over object properties 
 
 
  for (let i = 0; i <= 100; i++) { sum += i }  
 
  for(let key in obj) { }  
 
  while { }  
 
 
 In JavaScript, an object is a collection of properties (named values).
