₹3931.29
Steps to Solve
- Identify the problem
We are asked to find the cost of leveling a square field with a side of 20.9 m at a rate of ₹9 per square meter.
- Calculate the area of the square field
The area of a square is side * side or $side^2$. So, the area of the square field is $20.9 \times 20.9 = 436.81 \ m^2$.
- Calculate the total cost of leveling
The cost of leveling is ₹9 per square meter. So, the total cost is the area of the field multiplied by the cost per square meter. Total cost $= 436.81 \ m^2 \times ₹9/m^2 = ₹3931.29$.

More Information
The calculated cost represents the total expenditure required to level the square field at the given rate.
Tips
A common mistake is failing to square the side length when calculating the area of the square. Another common mistake is using the incorrect units or not paying attention to the units given in the problem.
