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 12 km/hr completes one round in 8 minutes, then the area of the park (in sq. m) is:
A. 15360 B. 153600
C. 30720 D. 307200

- Option B 153600
let length =3x and breadth=2x
perimeter=2(3x+2x)=10x
Distance =12000/60*8=1600
10x=1600
x=160
Area=480*320=153600 - 12 years agoHelpfull: Yes(3) No(0)
