# How to find the area and perimeter of a square

A square has 4 sides of similar length which are at right angles to each other.

## Answer: The area of a square is equal to the square of the length of its side and the perimeter of the square is 4 times the length of its side.

Let the length of the side of a square be 'a' units

## Explanation:

The area of the square = a² square units

The perimeter of the square = 4a units

Hence, the area of the square is equal to the square of the length of the side and the perimeter of the square is 4 times the length of its side.
