Question

An athlete takes 10 rounds of a rectangular park, 50 m long and 25 m wide. Find the total distance covered by him.

Answer 1

Length of the rectangular park =50 m
Breadth of the rectangular park =25 m
Total distance covered by the athlete in one round will be the perimeter of the park.
Now, perimeter of the rectangular park
$=2\times (length+breadth)=2\times (50+25)m$
$=2\times 75m=150m$
So, the distance covered by the athlete in one round is 150 m.
Therefore, distance covered in 10 rounds $=10\times 150m=1500m$
The total distance covered by the athlete is 1500 m.
