Question

Find the cost of fencing a rectangular park of length $87.5m$ and breadth $62.5m$ at the rate of $₹$$12permetre$.

Answer 1

Step 1: Perimeter of rectangular park

Length of rectangular park $\left(l\right)$ $=$$87.5m$

Breadth of rectangular park$\left(b\right)$ $=$$62.5m$

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

$$\begin{gathered} =2(87.5+62.5)m \\ =2\times 150m \\ =300m \end{gathered}$$

Step 2: Cost of fencing a rectangular park

Cost of fencing $1m$ $=$$₹$$12$

Cost of fencing $300m$$=$$₹$$12\times 300=₹3600$

Therefore, cost of fencing a rectangular park is $₹3600$.
