What is the correct answer?


The diffrence 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

Correct Answer :

D. 2520 m2

We have (l-b)=23 and 2(l+b)=206 or (l+b)=103
Solving the two equatoins, we get l=63 and b=40
l××b=63×40m2=2520 m2
