Question

A playground measures 300 m × 170 m.Find the cost of planting grass on this at the rate of Rs 80 per hectare.​

Answer 1

Answer :-

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

Area of field = Length × Breadth

${= 300×170}$

${=51000 sq. m}$

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

${= 0.408 p}$
