Find a cost of leveling a square field with 20.9m long side at the rate of Rs 10 per m.

Dear Student,

Assuming :

Find the cost of levelling a square field with 20.9 m long side at the rate of Rs 10 per m².

$$\begin{gathered} \mathrm{Length} \mathrm{of} \mathrm{each} \mathrm{side} \mathrm{of} \mathrm{square} \mathrm{field}, \mathrm{s} = 20.9 \mathrm{m} \\ \mathrm{Area} = {\mathrm{s}}^2 = 20.9 \times 20.9 = 436.81 {\mathrm{m}}^2 \\ \mathrm{Cost} \mathrm{of} \mathrm{levelling} 1 {\mathrm{m}}^2 \mathrm{area} = \mathrm{Rs} 10 \\ \mathrm{Cost} \mathrm{of} \mathrm{levelling} 436.81 {\mathrm{m}}^2 \mathrm{area} = 10 \times 436.81 = \mathrm{Rs} 4368.10 \end{gathered}$$
