Question

Find the perimeter of a park that is $63m$ long and $27m$ wide. Find the cost of fencing the park with a steel wire if the rate of fencing is $₹5$ per metre.

Answer 1

The Length of the park $=63m$

The breadth of the park $=27m$

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

$$\begin{gathered} =2(63+27) \\ =2\left(90\right) \\ =180m \end{gathered}$$

Cost of fencing $=Perimeter\times rate$

$$\begin{gathered} =180\times 5 \\ =900 \end{gathered}$$

Hence the cost of fencing is $₹900$
