The length of the rectangle is 1 m 25 cm, and the width is 5 times less. Find the side length of a square

The length of the rectangle is 1 m 25 cm, and the width is 5 times less. Find the side length of a square whose perimeter is equal to the perimeter of this rectangle.

We will solve this task in steps and explain each of them in detail.
1) 1 meter 25 centimeters = 125 centimeters – the length of the rectangle;
2) 125: 5 = 25 centimeters – the width of the rectangle, since it is 5 times less than the length, and the length is 125 centimeters;
3) 2 * (25 + 125) = 2 * 150 = 300 centimeters – the perimeter of a rectangle with a length of 125 centimeters and a width of 25 centimeters;
4) 300: 4 = 75 centimeters – the length of the side of the square, since its perimeter is 300 centimeters.
Answer: 75 centimeters.
