# Perimeter of a Square Calculator

Welcome to our Perimeter of a Square Calculator page.

We explain how to find the perimeter of a square and provide a quick calculator to work it out for you, step-by-step.

There is also a separate calculator which will find the length of the side of a square, if you already know the perimeter.

### Perimeter of a Square Examples

#### Perimeter of a Square Example 1

Find the perimeter of the square below. The length of each side of the square is 13cm.

The formula for the perimeter of a square is P = 4s, where P is the perimeter and s is the length of each side.

So this means that P = 4 x 13 = 52

So the perimeter of the square is 52 cm.

#### Perimeter of a Square Example 2

Find the perimeter of the square below. The length of each side of the square is 3 ¼ inches.

The perimeter of the square:

$P = 4 \times 3 {1 \over 4} = 4 \times {13 \over 4} = {52 \over 4} = 13$

So the perimeter of the square is 13 inches.

#### Perimeter of a Square Example 3

Find the perimeter of the square below. The length of each side of the square is 9.3 meters.

The perimeter of the square is P = 4 x 9.3 = 37.2

So the perimeter of the square is 37.2 m.

#### Perimeter of a Square Example 4

Use the perimeter of the square below to find the length of each side. The perimeter of the square is 35 cm.

The formula for the perimeter of a square is P = 4s, where P is the perimeter and s is the length of each side.

We can rearrange this equation in terms of the side length s to give us:

$s = P \div 4$

Substituting the value of P into this equation gives us:

$s = 35 \div 4 = {34 \over 4} = 8.75 cm$

So the length of each side is 8.75 cm.
