Question
The perimeter of a rectangular field is 240 meters, and
its length is 20% more than its breadth. What is the area of the field?Solution
Perimeter = 2(L + B) = 240 meters. L + B = 120 meters. Let breadth = B and length = 1.2B. B + 1.2B = 120. 2.2B = 120. B = 120 / 2.2 = 54.55 meters. L = 1.2 × 54.55 = 65.46 meters. Area = L × B = 65.46 × 54.55 = 3,571.49 ≈ 3,570.8 m². Correct Option: b
