The perimeter of a square can be calculated by adding all of the sides together. It is four times the length of each side of a square because all four sides are equal.
Perimeter of the square = Sum of the lengths of 4 sides
Example:
Find the perimeter of a square, whose side is 5 cm.
Perimeter of a square using the diagonal:
A square is a regular polygon with equal sides on all sides. In addition, the square's all four angles are equal and measures 90 degrees.
Using Pythagoras' theorem, we get the length of a square's diagonal as follows:
Example:
If the length of the square diagonal is 8 cm, then find the perimeter of a square.
