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
E . None of these
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
