Question

Find the cost of fencing a rectangular park of length $175m$ and breadth$125m$ at the rate of Rs $12$ per meter.

Answer 1

Given length of rectangular park = $l=175m$

breadth of rectangular park = $b=125m$

Cost of fencing for one meter = $Rs12$

Perimeter of rectangular park = $2(l+b)$

= $2(175+125)=2\left(300\right)=600m$

Cost of fencing $600m$ $=12\times 600=Rs7200$

Hence, the cost of fencing the rectangular park is $Rs7200$.
