Difference between the length &breadth of a rectangle is 10 m. If its perimeter is 206 m, then its area is?	Answers.
A) 2400 m ^ 2  B) 1500 m ^ 2  C) 2520 m ^ 2  D) 1200 m ^ 2  E) 2580 m ^ 2

Rationale: solving the two equations , we get : l = 30 and b = 40 . area = ( l x b ) = ( 30 x 40 ) m 2 = 1200 m ^ 2 d
Answer: D
