Question

the area of a rectangle is 2592 sq. m. and it's length is 54 m. A boy runs around it at the rate 4 km/hr.how long will he take to go 5 times around it?

Answer 1

Breadth of the field = Area/length = 3584/64 = 56m

Perimeter of the field = 2*(64+56) = 240m

The boy covers five rounds of the field so the total distance covered by the boy = 240*5 = 1200m or 1.2km

Now time = distance/speed = 1.2/6 = 0.2 hrs = 12min

So the boy will go five times around the field in 12 min.

Answer 2

Hola mate..

Answer:-

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.
