Question

The cost of fencing a rectangular park of length $150m$ and breadth $100m$ at the rate of $Rs20\mathrm{per}\mathrm{meter}$ is $\_\_\_\_\_$

Answer 1

Finding the cost of fencing:

Perimeter of rectangular park $=2(length+breadth)$

$=2(150+100)$

$=500$

Cost of fencing at the rate of $Rs20$ per meter $=500\times 20$

$=10000$

Therefore, the cost of fencing a rectangular park of length $150m$ and breadth $100m$ at the rate of $Rs20\mathrm{per}\mathrm{meter}$ is $Rs10000.$
