Question

Each side of a square field measures $85\text{m}$. The distance covered by a man going around the field $5$ times is _______ .

• A. $1600\text{m}$
• B. $1800\text{m}$
• C. $1500\text{m}$
• D. $1700\text{m}$

Answer 1

Answer: (D)

$1700\text{m}$

$\Rightarrow$ Each side of square field $=85\text{m}$

$\Rightarrow$ Distance covered by man going around the field $1^{st}$ time $=4\times \text{side of square field}$

$\Rightarrow$ Distance covered by man going around the field $1^{st}$ time $=4\times 85\text{m}$

$\therefore$ Distance covered by man going around the field $1^{st}$ time $=340\text{m}$

$\therefore$ Distance covered by man going around the field $5$ times $=340\times 5=1700\text{m}$
