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.
