★ To Find :

  • We hqve ro find the cost of levelling the square at ₹22 per meter.

\rule{200}{1}

As, we have given the cost of levelling square in ₹ 15 per meter is ₹19,935.

So, If we devide total cost at ₹15 per meter by 15 we will GET tge area of the square.

\sf{\dashrightarrow Area = \frac{\cancel{19935}}{\cancel{15}}} \\ \\ \sf{\dashrightarrow Area = 1329} \\ \\ \Large{\implies{\boxed{\boxed{\sf{Area = 1329 \: m^2}}}}}

\rule{200}{2}

Now,

If we will multiply the area of squqre by the 22 we will get cost of levelling at ₹22 per meter.

→ Cost of levelling = 1329 \times 22

→ Coat of levelling = ₹ 29,238
