| Let’s find the width of the given rectangle.
According to the condition of the problem, the length of this rectangle is 1/4 m, and its area is 75 cm2.
Let’s express the length of this rectangle in centimeters.
There are 100 centimeters in one meter, therefore, 1/4 of a meter is equal to 100/4 = 25 centimeters and the length of this rectangle in centimeters is 25 cm.
We can make the following equation:
x * 25 = 75.
Solving this equation, we get:
x = 75/25;
x = 3 cm.
Find the perimeter of this rectangle:
2 * (25 + 3) = 2 * 28 = 56 cm.
Answer: the perimeter of this rectangle is 56 cm.
