Answer :-

To find the cost of planting grass , we have to find area of the field.

Area of field = Length × Breadth

[tex]{= 300×170}[/tex]

[tex]{=51000 sq. m}[/tex]

Now convert into hectare.

1 hectare = 10000m sq.

51000 / 10000

So area field = 5.1 hectare sq.

Now cost = 5.1 x 0.80 p

[tex]{= 0.408 p}[/tex]
