Area - General Aptitude

Q1:

The difference between the length and breadth of a rectangle is 23 m. If its perimeter is 206 m, then its area is:

A 1520 m2

B 2420 m2

C 2480 m2

D 2520 m2

ANS:D - 2520 m2

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.
