Question

The length and breadth of a rectangle are in the ratio 13 : 2. What is the perimeter if the area is 104 sq. meters?

A

60 meters.

B

62 meters.

C

58 meters.

D

64 meters.

Soln.
Ans: a

Let L = 13x and B = 2x. We are given (13x × 2x) = 104, which gives x = 2. So perimeter = 2 × ((13 × 2) + (2 × 2)) × = 60 meters.
