Perimeter: – The total length that a square's boundary covers is defined as the perimeter. – A square's perimeter is calculated by summing the lengths of all of its sides.

– The perimeter of a square can be computed 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 Square Formula: – The perimeter of a square can be calculated using the following mathematical formula Perimeter of square, (P) = 4 × Side

Example: Calculate the perimeter of a square with one side measuring 5 cm. Sol: Given, side of a square = 5cm

[{"selector":"#anim-1c25b7e2-6bca-4442-bfe9-5cdc25137a55","keyframes":{"opacity":[0,1]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-fc6bfd80-d5e3-4712-a648-f1183a746031","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

We know that in a square all the sides are equal. so, the perimeter of a square = 4 × (side) = 4 × (5) = 20 cm Therefore Perimeter of a square = 20 cm

[{"selector":"#anim-73075822-a8a8-496d-bcf8-0e3742c338b5","keyframes":{"opacity":[0,1]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-e91e8fb0-5c34-4ca1-acf8-981c675dc1c5","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

Example 2: If the perimeter of the given square is 12 cm. What will be the length of its side? Solution: Given, the perimeter of the square = 12 cm. Let the side length be ‘a’ cm.

[{"selector":"#anim-d361f0aa-47d2-4f4b-a34a-da66b1ee94e8","keyframes":{"opacity":[0,1]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-776aaec5-5ef6-4b4a-9f0c-98448de7f620","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

We know that The perimeter of a square = 4 × (side) 12 = 4 × (a) a = 3 cm Hence side of a square length = 3 cm.
