Question

Find the cost of fencing a rectangular park of length $40\text{m}$ and breadth $25.5\text{m}$ at the rate of $₹12$ per meter .

Answer 1

Finding the cost of fencing a rectangular park :

For finding the cost of fencing, we first find the perimeter of the park.

Given that, length of the park $=40\text{m}$

Breadth of the park $=25.5\text{m}$

Now,

Perimeter of the park $=2\times (\text{length +breadth)}$

$$\begin{gathered} =2\times (40+25.5) \\ =2\times (40.0+25.5) \\ =2\times (62.5) \\ =125\text{m} \end{gathered}$$

$\therefore$Cost of fencing the park per meter $=$$₹12$

Cost of fencing the park $=125\times ₹12=₹1500$

Hence, the cost of fencing the park is $₹1500$
