Calculate the Perimeter of a Square

How to calculate the perimeter of a square in 2 methods? Calculator Market brings you the solution with its formulas to help you to find the result.

The 2 Formulas for Calculating the Perimeter of a Square

Let’s say the following: P = Scope | A = Side | S = Area

To calculate the Perimeter of a Square from the side, use the following formula:

P = 4A

Indeed, the perimeter of the square is equivalent to the total length of its sides placed end to end. Since the property of the square is to have 4 equal sides, it is therefore logical that the perimeter of a square is equal to 4 times its side.
To calculate the Perimeter of a square from its area:

The area of ​​a square is equal to its squared side. If you want to get the square perimeter, then you have to get his side. So:

  • A = √S
  • P = 4A
  • P = 4 (√S)

P = 4 (√S)
