The perimeter of a square is calculated by adding the lengths of all four sides together. Since all sides of a square are equal in length, you can multiply the length of one side by 4 to find the perimeter. In this case, if the square is 72 centimeters on each side, the perimeter would be 72 cm x 4 = 288 cm.

72 centimeters of what.
im gonna assume the area is 72 cm. so it would be 72 sq cm
your perimeter would be around 33.94
you need to take the squared root of 72. this gives the length of one side. then multiply this number by 4 since there are four sides to a square.
72 because if the area is 324 and you make a block chart and count the sides it will equal 72
20 centimeters.
72
The perimeter of this square measures 4 x 1 = 4 decimeters. As 1 decimeter = 10 centimeters then 4 decimeters = 4 x 10 = 40 centimeters.
The square root of 324 is 18 so the perimeter must be 4*18 = 72 cm
