Question

The length and breadth of a rect- angular playground are in the ratio 7:5. The perimeter of the playgro- und is 288 m. What is its area? d​

Answer 1

let

length = 7x

breadth = 5x

given

perimeter = 288

2(l+b) = 288

2(7x+5x)=288

12x=144

x=12

So, length = 84

Breadth = 60

Area = b×h = 84×60 = 5040
