The area of rectangular field is 3584m square and its length is 64m. A boy runs around the field at the rate of 6km/h. How long will be take to go 5times around it.

Answer 1

A = L x W
You know A and L, solve for W.

Perimeter = 2L + 2W. Substitute and solve for perimeter.
dustabce boy runs is 5 x perimeter= ?

6 km/hr = 6000 m/hr.

distance = rate x time. You know the rate and distance, substitute and solve for time in hours.
