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.
