Question

a playground measures 300m × 170m. find the cost of planting grass on this at the rate of rupees 80 per hectare

Answer 1

Given: Length of the playground is 300m, breadth is 170m and the rate is 80 rupees per hectare.

To find: The total cost.

Answer:

Let us first find the area of the field.

Area = length*breadth

Substituting the given values,

Area = 300*170 = 51000m^2

Now let us convert this measure to hectares.

To convert m^2 to hectares, we have to divide the area by 10000.

So 51000m^2 = 51000/10000 = 5.1 hectares.

Now cost per hectare = 80.

Therefore cost for 5.1 hectares = 80*5.1 = 408 rupees.

Hope it helps :)

Answer 2

Answer:

$ 408

Step-by-step explanation:

First Step:- Multiply 300m by 170m

= 51,000.

Second Step:- 1 hectare = 10,000 square metres

Third Step:- Divide 51,000 ÷ 10,000

= 5.1 hectares.

Fourth Step:- Per hectares $ 80, So therefore

5.1 hectares = ($ 80 × 5.1 ) hectares

= $ 408.
