The difference between the length and breadth of a rectangle is 23 m. If its perimeter is 206 m, then its area is:
A) 2520
B) 2420
C) 2320
D) 2620
Answer: A) 2520
Explanation:
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) = 2520 sq.m
