The difference between the length and breadth of a rectangle is 23 m. If its perimeter is 206 m, then its area is: Pick.
A) 1520 m2  B) 2420 m2  C) 2480 m2  D) 2520 m2  E) 2645 m2
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) m2 = 2520 m2.   Answer: 2520 m2
