The ratio between the length and the breadth of a rectangular plot is 7 : 5. If the perimeter of the plot is 72 metres, what is its area?  Choices
A) 315 sq.metres	B) 260 sq.metres	C) 280 sq.metres	D) 380 sq.metres	E) None of these
Let the length and breadth be 7x and 5x respectively.   Then, P = 2(7x + 5x) = 72 â‡’ x = 3   Area = 7 Ã— 3 Ã— 5 Ã— 3 = 315 sq.m.   315 sq.metresnswer 315 sq.metres
