Cost of levelling square lawn at ₹15/m² = ₹19935
Area of square lawn = ₹19935 / (₹15/m²) = 1329m²
Cost of leveling the lawn at ₹22/m²
= 1329m² × ₹22/m²
= ₹29,238
Area of square lawn = ₹19935 / (₹15/m²) = 1329m²
Cost of leveling the lawn at ₹22/m²
= 1329m² × ₹22/m²
= ₹29,238

Square lawn :
Area of square lawn = l²
cost of levelling the lawn at the rate of 15 Rs. per metre square if given by 19935 Rs.
ATQ
19935 = area of square lawn x rate of leveling the lawn
19935 = l² x 15
19935/15 = l²
1329m² = area
In other case
rate of levelling the lawn is 22 Rs per m²
so cost of levelling the lawn = 22 x 1329 = 29238 Rs.
