Question

An athlete takes $15$ rounds of a rectangular park $30\text{m}$ long and $20\text{m}$ wide . Find the total distance covered by him .

Answer 1

Finding the distance covered in $15$ rounds :

Given :

Length of the rectangle $=30\text{m}$

Breadth of the rectangle $=20\text{m}$

Now,

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

$$\begin{gathered} =2\times (30+20) \\ =2\times \left(50\right) \\ =100\text{m} \end{gathered}$$

Distance of $1$ round $=100\text{m}$

Distance of $15$ rounds $=15\times 100=1500\text{m}$

Therefore, distance covered in $15$ rounds by athlete is $1500\text{m}$
