Solution :
To find the distance We have to find the perimeter of the rectangular field.
We know that,
\large{\star{\underline{\boxed{\sf{Perimeter = 2(Length + Breadth)}}}}}⋆Perimeter=2(Length+Breadth)
Perimeter = 2(1500 + 750)
Perimeter = 2(2250)
Perimeter = 4500 m
\large{\star{\underline{\boxed{\sf{Perimeter = 4500 \: m}}}}}⋆Perimeter=4500m
\rule{150}{2}
He had to take 4 rounds. So, multiply perimeter by 4
Distance = 4500 * 4
Distance = 18000 m = 18 km
\large{\star{\underline{\boxed{\sf{Distance = 18 \: km}}}}}⋆Distance=18km
\rule{200}{2}
\large{\star{\underline{\boxed{\sf{Time = \frac{Distance}{Speed}}}}}}⋆Time=SpeedDistance
Time = 18/4.5
Time = 4 hr
\large{\star{\underline{\boxed{\sf{Time = 4 \: hours}}}}}⋆Time=4hours
