Question

What distance Aslam will travel if he takes three rounds of a square park of side $50\text{m}$?

• A. $100\text{m}$
• B. $600\text{m}$
• C. $2500\text{m}$
• D. $10000\text{m}$

Answer 1

The correct option is B

$600\text{m}$

Step 1: Find the perimeter of the park

The perimeter $P$ of the square with side $s$ is given by, $P=4\times s$.

Substitute $s=50$ into $P=4\times s$ to find the perimeter of the square.

$\begin{array}{rcl}P& =& 4\times 50\\ & =& 200\text{m}\end{array}$

Step 2: Find the total distance aslam travelled.

As he takes three rounds, multiply the perimeter of the park by $3$.

$200\times 3=600\text{m}$

Hence, the distance traveled by him in three rounds is $600\text{m}$. So, the correct option is $\mathit{b}$.
