Question

the area of rectangular field is 3584m2 and its length is 64 m. A boy runs around the field at the rate of 6km/h.How long will he take to go 5 times around it

Answer 1

heya!!

here's ur answer frnd...

given:-

length of the field=64m

area of the field=3584m²

l×b=3584m²

64×b=3584m²

b=3584/64

b=56m

perimeter of the field=2(l+b)

=2(64+56)

=2×120

=240m

if the boys runs 5 times around it, then the total distance covered by him=240×5

=1200m

=1.2km

time will it take to complete 6km=1hour

time taken to complete 1.2km=1.2/6

=0.2hour

=12minutes

hope this helps...
