Answer 1

given

length of play ground=80m

breadth of play ground=35m

perimeter =2(l+b)

=2(80×35)

=2(105)

=210 m

rate of the boy =1.5m per sec

time taken by the boy to walk 2 times around play ground=2×210÷1.5

=420÷15

=28 sec

thus ,the boy take 28 sec to make two rounds.

hey mate ,I hope that it will help you.
