Answer 1

★ Given :

• Cost of levelling square at ₹15 per meter is ₹19,935.

$\rule{200}{1}$

★ 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

$\therefore$ Cost of levelling the square lawn at ₹ 22 per meter is ₹ 29,238.
