Question

The cost of fencing a rectangular park of length $250$ m and breadth $150$ m at the rate of Rs $10$ per meter is Rs. _____

Answer 1

Step 1: Finding the perimeter of the rectangular park

It is given that the length of the rectangular park is $250m$ and breadth of the rectangular park is $150m$

We know that perimeter of rectangle$=2\left(l+b\right)$ where $l$ is length and $b$ is breadth.

So, perimeter of the given rectangular park$=2\left(250m+150m\right)$

$=2\times 400m$

$=800m$

Step 2: Finding the cost of fencing the rectangular park

Cost of fencing$=$ Rate of fencing $\times$Perimeter

$=₹10\mathrm{per}m\times 800m$

$=₹8000$

Hence, it will cost $₹8000$ to fence the rectangular park.
