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.
This calculator finds the perimeter of a square when the side length is known.
This calculator finds the side length of the square when the perimeter is known.
The perimeter of a shape is the distance all the way around the outside of the shape.
You can find the perimeter of any shape by adding up all of the side lengths.
The formula for the perimeter of a square is:
P = 4s
where P is the perimeter and s is the length of one of the sides.
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.
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.
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.
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.
