To find the cost of leveling the garden, we first need to determine the area of the square garden.
The area \( A \) of a square is given by the formula:
\[ A = \text{{side}}^2 \]
In this case, the side of the square is represented by \( x \) meters.
So, the area \( A \) is:
\[ A = x^2 \]
Given that the cost of leveling the garden is ₹5.25 per square meter, the total cost \( C \) can be calculated by multiplying the area \( A \) by the cost per square meter:
\[ C = \text{{Area}} \times \text{{Cost per square meter}} \]
\[ C = x^2 \times 5.25 \]
Now, Neetu can calculate the cost of leveling the garden once she knows the side length \( x \) of the square yard.
