The perimeter of the first square is 28 cm. Find the perimeter of the second square, the side length of which is 5 cm

The perimeter of the first square is 28 cm. Find the perimeter of the second square, the side length of which is 5 cm shorter than the side length of the first square.

1) Let X be the side of the first square.

2) Based on the condition of the problem, we write the equation:

2 (2 X) = 28;

4 X = 28;

X = 7;

3) The side length of the second square is:

7 – 5 = 2;

4) The perimeter of the second square is:

2 * 2 * 2 = 8 cm.

Answer: The perimeter of the second square is 8 cm.
