Question

Find the cost of fencing a rectangular garden of length $175m$ and breadth $125m$ at the rate of $₹12$ per metre.

Answer 1

Step 1: Find the perimeter of the rectangular garden

The perimeter of the rectangular garden$=2(l+b)$

$\begin{array}{rcl}& =& 2(175+125)\\ & =& 2\left(300\right)\\ & =& 600m\end{array}$

Thus, perimeter of rectangular garden is $600m$

Step 2: Find the cost of fencing

The cost of fencing the rectangular garden $=perimeter\times \cos tpermetre$

$$\begin{gathered} =600\times 12 \\ =₹7200 \end{gathered}$$

Hence, the cost of fencing the rectangular garden is equal to $₹7200.$
