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

Decision.
1) How many centimeters is the length of a rectangle if it is equal to 1 m 25 cm?
1 m 25 cm = 100 cm + 25 cm = 125 cm.
2) How many centimeters is the width of the rectangle if it is known from the condition of the problem that the width of the rectangle is five times less than the length?
125: 5 = 25 (cm).
3) What is the perimeter of this rectangle?
(125 + 25) ∙ 2 = 300 (cm).
4) What is the length of the side of a square whose perimeter is equal to the perimeter of this rectangle?
300: 4 = 75 (cm).
Answer: 75 cm is the length of the side of a square, the perimeter of which is equal to the perimeter of this rectangle.
