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

63 - 40 = 23.
i.e. l - b = 23.
And 63 * 40 = 2520.
i.e. l - b = 23.
And 63 * 40 = 2520.
