# Perimeter of a Square Formula

The total distance outside the square is the perimeter of the square. We know that the 4 sides and the perimeter of the sum of the length of all the 4 sides. All the sides of a square are equal and hence the perimeter is taken as four times the one side.

**Perimeter of a Square Formula** is given as,

$\large Perimeter\;of\;a\;Square(p)=4a$

Where,

a is the side of the square

### Solved Examples

**Question 1: **Find the perimeter of a square whose side is 16 cm ?

**Solution:**

Given,

Side of the square = a = 7 cm

Perimeter of a Square = 4a

= 4 x 16

= 64 cm
