Answer:

The cost of fencing is Rs.1460.

Step-by-step explanation:

Given : The cost of leveling a square lawn at Rs . 2.50 per square meter is Rs. 13322.50.

To find : The cost of fencing it at the rate of Rs .5 per meter?

Solution :

The cost of leveling a square lawn is Rs.13322.50

$\text{Cost}=\text{Area}\times \text{Rate}$

$13322.50=\text{Area}\times 2.50$

$\text{Area}=\frac{13322.50}{2.50}$

$\text{Area}=5329$

Area of the square lawn,

$A=side^2$

$5329=side^2$

$(73)^2=side^2$

Side of the lawn = 73 m

Now, Perimeter of the square lawn is

$P=4\times side$

$P=4\times 73$

$P=292m$

The cost of fencing it at the rate of Rs .5 per meter

The cost of fencing is

$C=292\times 5=1460$

Therefore, The cost of fencing is Rs.1460.
