Question

The length and breadth of a rectangle are in the ratio 13 : 7. What is the area if the perimeter is 200 meters?

A

2275 sq. meters.

B

2277 sq. meters.

C

2273 sq. meters.

D

2279 sq. meters.

Soln.
Ans: a

Let L = 13x and B = 7x. We are given 2 × (13x + 7x) = 200, which gives x = 5. So area = L × B = (13 × 5) × (7 × 5) = 2275 sq. meters.
