Find the perimeter of a square with a side of 15 cm, and wait for its side by 6 cm and find a new perimeter in a row.

In order to find the perimeter of a square, it is necessary to sum up all of its sides or multiply the indicated value of the length of any side by 4.

We get:

15 + 15 + 15 + 15 = 60 cm.

15 * 4 = 60 cm.

Find the side length of the new square.

15 – 6 = 9 cm.

From this it follows that its perimeter will be:

9 * 4 = 36 cm.

Answer: The perimeters of the squares are 60 and 36 centimeters.
