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 9 km / hr completes one round in 5 min , then the area of the park ( in sq . m ) is ?
"perimeter = distance covered in 5 min . = ( 9000 x 5 ) / 60 m = 750 m . let length = 3 x metres and breadth = 2 x metres . then , 2 ( 3 x + 2 x ) = 750 or x = 75 . length = 225 m and breadth = 150 m . area = ( 225 x 150 ) m 2 = 33750 m d"
