The length of the rectangle is 39.2 m and it is 7 times greater than the width. Find the perimeter of the rectangle.

1. Find the width of the rectangle if it is 7 times less than the length:
39.2 / 7 = 5.6 m.
2. Find the perimeter of the rectangle by adding twice the value of its length and width:
Perimeter = 2 * 5.6 + 2 * 39.2 = 11.2 + 78.4 = 89.6 m.
3. Let’s translate the resulting value of the perimeter in cm:
89.6 m = 8960 cm.
Answer: the correct answer is d) the perimeter of the rectangle is 8960 cm.
