Answer 2

Answer:

your answer is ↓↓

Step-by-step explanation:

total cost of levelling the square lawn at RS. 15 per sq meter

area of lawn = total cost / cost per sq . m = 6000/15

area of lawn = 400 sq . m

area of square = side × side

so , least side of = √400

each side of lawn = 20 m

now

perimeter of the sq . lawn = 4 × side

perimeter = 4 × 20

perimeter of the sq . lawn = 80 m

cost of fencing the sq . m lawn = RS. 25 per m

total cost of fencing the sq . lawn = 25 × 80 = rs 2000

so, the cost of fencing the sq . lawn is rs . 2000
