Find the perimeter of a square whose side length is 13cm.

Let’s remember what a perimeter is. The perimeter is the sum of the lengths of all sides. Therefore, in order to find the perimeter of a square, we need to add the lengths of all four sides. But since all four sides of a square are equal, therefore, we can multiply the length of its side by the number of sides, that is, by 4. So, we calculate the perimeter of the square whose side length is 13 cm.
P = 13 + 13 + 13 + 13 = 52 cm or
P = 13 * 4 = 52 cm.
Answer: The perimeter of the square is 52 cm.
