Question

Sweety runs around a square park of side 75 m. Bulbul runs around a rectangular park with length 60 m and breadth 45 m. Who covers less distance?

Answer 1

$\text{Distance covered by Sweety} = \text{Perimeter of square park}$
Perimeter of square = $4 \times side$
= $4 \times 75 = 300$ $m$
Thus, distance covered by Sweety is $300$ $m$.
Now, $\text{distance covered by Bulbul} = \text{Perimeter of rectangular park Perimeter of rectangular park}$
= $2 \times (length + breadth)$
= $2 \times (60 + 45)$
= $2 \times 105$
= $210$ $m$

Thus, Bulbul covers the distance of $210$ $m$ and Bulbul covers less distance.
