Question

Five bags of fertiliser covers 15 square metres. What area of lawn could be covered with 30 bags of fertiliser?

Answer 1

We can solve the problem by setting up a proportion where the amount of fertiliser is directly proportional to the area of lawn covered.

Let x be the area of lawn covered by 30 bags of fertiliser.

Then, we can write the proportion as:

5 bags / 15 sqm = 30 bags / x sqm

To solve for x, we can cross-multiply and simplify:

5 * x = 15 * 30

x = 90 sqm

Therefore, 30 bags of fertiliser can cover an area of 90 square meters.
