Question

The ratio of length and breadth of a rectangular park is 6 : 3.
If a squirrel running along the boundary of the park at the speed of 24 km/hr completes one round in 12 minutes, find the area of the park in square meters.

Answer 1

24 km/hr=24000/60 m/min=40 m/min
40 m/min*12 min=480 m perimeter of park
(6+3)*2x=480 --> x= 30
6*30=180 m length
3*30=90 m breadth
Area= 180*90 m^2= 16200 m^2
