First find the breadth
Area=2592sq m
length = 54 my
breadth = ?
b = area÷length
2592÷54= 48
perimeter of a rectangle = 2 ( l+b )= 2 (54+48)m=2×102=204m
perimeter is 204m
distance will he cover in 5times= 204m×5=1020m
time = distance÷speed = 1020÷4 = 255 hours
he will take 255hrs to go 5times around it.
