The difference between the length and breadth of a rectangle is 42 m. If its perimeter is 280 m, then its area is:  Choose the correct choice from the following choices.
A) 1520 m2  B) 4250 m2  C) 4459 m2  D) 4092 m2  E) None
EXPLANATION   We have: (l â€“ b) = 42 and 2(l + b) = 280 or (l + b) = 140.   Solving the two equations, we get: l = 91 and b = 49.   Area = (l x b) = (91x 49) m2 = 4459 m2.   Answer 4459 m2
