Step-by-step explanation:

length is 80 m

breadth is 35 k

Rate of walking is 1.5m/s

distance covered by boy = 3 × perimeter of playground

=3×2(length+ breadth)

=6(80+35)

=6×115

=690 m

time taken by boy to cover distance = distance/rate of walking

=690/1.5

=460 Seconds

Answer:

The boy will take 460 seconds or 4 minutes 20 seconds to go three times round the field.

Step-by-step explanation:

   Given,

Length of playground = 80 m

Breadth of playground = 35 m

Number of rounds the boy needs to go round the field = 3 times

Number of metres the boy will go = 3*{2*(80+35)}m

                                                         = 690 m

Speed of the boy = 1.5 ms^-1

Time which will be taken by the boy = 690/1.5

                                                             = 1380/3

                                                             = 460 seconds

Therefore, The boy will take 460 seconds or 4 minutes 20 seconds to go three times round the field.
