How to find the perimeter of a square?

A square is a parallelogram with equal sides and right angles. How to find the perimeter of a square? A perimeter is the sum of all sides of a square.

The perimeter of the square (P) is equal to the sum of 4 lengths of itsides, and since the sides of the square are all the same, the formula is obtained as one side length of the square (h) multiplied by 4 (the number of sides of the square), or

P = 4 * h

So, for example, the perimeter of a square with a side of 5 cm will be as follows: 5x4 = 20. 20 cm - the perimeter of this square.
