Question

If the cost of fencing for 1 m of the figure given below is ₹25, then the cost of fencing the entire perimeter is .

• A. ₹1,25,000
• B. ₹1,76,000
• C. ₹2,50,000
• D. ₹2,25,000

Answer 1

The correct option is C ₹2,50,000

We have to find the cost of fencing of the given figure.

$\text{Length (l) = 3 km}$
$\text{Breadth (b) = 2 km}$

Let's find the perimeter first.


The perimeter of the given figure is 10 km.

Cost of fencing of 1 m = ₹25

Now, convert the perimeter into m.

$\text{We know that,}$
$\text{1 km =}$ $\text{1000 m}$


Hence, multiply 10 with 1000.

$\text{So, 10 km}=10\times 1\text{km}$
$=10\times 1000\text{m}$
$=10,000\text{m}$

Now, calculate the cost of fencing.


Therefore, the total cost of fencing is ₹2,50,000.
