Difference between the length &breadth of a rectangle is 10 m. If its perimeter is 60 m, then its area is??
Pick one
A) 2000 m^2
B) 200 m^2
C) 2520 m^2
D) 2556 m^2
E) 2534 m^2
l -b = 10   2 (l+b)= 60 =&gt; l + b = 30   2 l = 40 =&gt; l = 20 so b = 10   area of the rectangle = l x b = 20 x 10 = 200 m^2   Answer : 200 m^2
<result>B</result>
