The perimeter of a rectangle garden is 42. The width of the rectangle is 75% of its length. What is the area of the rectangle?
- 108m²
- 96m²
- 192m²
- None of these
Explanation
Let's denote the length as L and width as W.
Given W = 0.75L or W = (3/4)L
Perimeter = 2(L + W) = 42
2(L + 3L/4) = 42
2(7L/4) = 42
7L/2 = 42
7L = 84
L = 12
W = (3/4)*12 = 9
Area = L * W = 12 * 9 = 108
