Question

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

Answer 1

Step 1: Finding the distance covered by Sweety

Given that, side of square $=75\text{m}$

We know that,

Perimeter of square $=4\times \text{side}$

Therefore,

Perimeter of the square $=4\times 75=300\text{m}$

Hence, distance covered by Sweety is $300\text{m}$

Step 2: Finding the distance covered by Bulbul

Given that, Length of rectangle $=60\text{m}$

Breadth of rectangle $=45\text{m}$

We know that,

Perimeter of rectangle $=2\times (\text{length+breadth)}$

Therefore,

Perimeter of the rectangle $=2\times (60+45)$

$$\begin{gathered} =2\times \left(105\right) \\ =210\text{m} \end{gathered}$$

Hence, distance covered by Bulbul is $210\text{m}$

As $300\mathrm{m}>210\mathrm{m}$

Therefore, Bulbul covers less distance than Sweety .
