the ratio between the length and the breadth of a rectangular park is 3 : 2 . if a man cycling along the boundary of the park at the speed of 13 km / hr completes one round in 8 minutes , then the area of the park ( in sq . m ) is
"perimeter = distance covered in 8 min . = 18000 x 8 m = 2400 m . 60 let length = 3 x metres and breadth = 2 x metres . then , 2 ( 3 x + 2 x ) = 2400 or x = 240 . length = 720 m and breadth = 480 m . area = ( 720 x 480 ) m 2 = 345600 m 2 . a"
