Jawaban:

He will take 0.255 hours to go 5 times around it.

Step-by-step explanation:

Area of rectangular field = 2592 sq.m.

Length = 54 m

Area of rectangular field =

So,

Breadth = 48 m

Perimeter of field =2(l+b)=2(54+48)=204 m

So, Distance traveled in 1 round = 204 m

Distance traveled in 5 rounds = 204 \times 5 =1020 m

1000 m = 1 km

1020 m = 1.02 km

Speed of boy = 4 km \hr

Hence he will take 0.255 hours to go 5 times around it.
