Answer:
It is rectangular park and rectangle has equal opposite sides.
length of park = 104 m
width = 56m
One round of park = 104+104+56+56
= 320m
five rounds of park = 5×320
= 1600m
i.e 1.6 km
speed of anjali = 4 km /h
time taken = Distance /speed
= 1.6/4
= 0.4
time taken = 0.4 hours
or
= 0.4 × 60 mins
time = 24 mins
