Question

A rectangular field is $50m\times 40m$. Ramesh goes $20$ times around it. How much distance does he cover?

Answer 1

The distance covered will be the number of times Ramesh covers the total perimeter of the rectangular field.

Perimeter of the rectangular field will be $=2(l+b)=2\left(50+40\right)=2\times 90=180m$

As he covered this distance for $20$ times so the total distance covered will be $20\times 180=3600m$.

Thus, Ramesh covers a total distance of $3600m=\frac{3600}{1000}=3.6km$.
