The ratio between the length and the breadth of a rectangular plot is 7 : 5. If the perimeter of the plot is 216 metres, what is its area?  Select the correct option
A) 1325 sq.metres B) 1260 sq.metres C) 2835 sq.metres D) 3380 sq.metres E) None of these
Let the length and breadth be 7x and 5x respectively.   Then, P = 2(7x + 5x) = 216 â‡’ x = 9   Area = 7 Ã— 9 Ã— 5 Ã— 9 = 2835 sq.m.   Answer 2835 sq.metres
