Answer 1

ATQ, the cost of leveling the square lawn at 15 per m² is 19935.

therefore area of the square lawn = 19935/15

= 1329m²

now, it's a square lawn. hence it's all sides are equal.

➡ side² = area of the square lawn

➡ side² = 1329m²

➡ side = √1329

➡ side = 36.45m (approximately)

total cost of fencing the square lawn @ 22 per meter = 36.45 × 22 = 801.9
