Difference between the length and breadth of a rectangle is 23 m. Ifits perimeter is 206 m, then its area is??  Choose the correct choice from the following.
A) 1220 m ^ 2 B) 1520 m ^ 2 C) 2520 m ^ 2 D) 2600 m ^ 2 E) 3420 m ^ 2

Rationale: 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 ) m 2 = 2520 m ^ 2 c
Answer: C
