Question

What is a rectangle?​

Answer 1

Answer:

a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.

Answer 2

A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees. Hence, it is also called an equiangular quadrilateral. 

Since, the opposite sides are equal and parallel, in rectangle, therefore, it can also be termed as a parallelogram. 

Shape of Rectangle:-

A rectangle is a two-dimensional flat shape. In an XY plane, we can easily represent a rectangle, where the arms of x-axis and y-axis show the length and width of the rectangle, respectively. 

Rectangular Shaped Objects:-

The most common everyday things or objects we see and are rectangular in shape is Television, computer screen, notebook, mobile phones, CPU , Notice boards, Table, Book, TV screen, Mobile phone, Wall, Magazine, Tennis court, etc.

Properties of Rectangle:-

• The properties of rectangle are given below:

• It has four sides and four vertices

• Each vertex has angle equal to 90 degrees

• The opposite sides are equal and parallel

• Diagonal bisect each other

• Perimeter is equal to twice of sum of its length and breadth

• Area is equal to product of its length and breadth

• It’s a parallelogram with four right angles.

• Sum of all interior angles equal to 360 degrees

Perimeter of a Rectangle:-

The perimeter of a rectangle is defined as the total distance covered by the outer boundary of the rectangle. It is measured in unit length. The formula of perimeter is given by:

• Perimeter, P = 2 (Length + Width) 

Area of Rectangle:-

Area is the region covered by a two-dimensional shape in a plane. It is measured in square units. Therefore, the area of the rectangle is the area covered by its outer boundaries. It is equal to the product of length and width. 

• A = Length × Width Unit²
