Question

one side of a square is 300 M what is the cost of planting grass and this plot at the rate of rupees 75 per hectare

Answer 1

Side of square = 300 m

So the area of square = [300]^2

= 90000 sq.m

cost of planting grass per hectare= 75 rupees

since 90000 sq.m = 9 hectares

so total cost of planting grass = 75 x 9= 675 rupees.
