The perimeter of the rectangle is 54 m, its length is 15.125 m. Find the perimeter of a square

The perimeter of the rectangle is 54 m, its length is 15.125 m. Find the perimeter of a square with a side equal to the width of the rectangle.

First of all, let’s find the width of the rectangle. By the condition of the problem, the perimeter is known, which is equal to the product of the number 2 by the sum of the length and width. In this way:

54: 2 = 27.

27 – 15.125 = 11.875 (m) – the width of the rectangle.

The perimeter of a square with a side of 11.875 m is found by the product of a known side by 4:

11.875 * 4 = 47.5 (m).

Answer: 47.5 m.
