Question

The difference between the length and breadth of a rectangle is 23 m. If its perimeter is 206 m, then its area is:

Options:

A . 1520 m²

B . 2420 m²

C . 2480 m²

D . 2520 m²

Answer: Option D

We have: (l - b) = 23 and 2(l + b) = 206 or (l + b) = 103.

Solving the two equations, we get: l = 63 and b = 40.

Area = (l x b) = (63 x 40) m² = 2520 m².
