Sonya wants to buy grass seed to cover her whole lawn, except for the pool. The pool is 4 5 6 m by 2 1 3 m. Find the area the grass seed needs to cover.

found out from the local garden centre that I will need 55g of seed for each m2.

So the total amount of seed I will need is:

41 × 55g = 2,255g

But the area calculation was only a rough estimate, so maybe I need to buy, say, 5% extra.

That makes 2,255g × 105% = 2,368g

Or about 2.4 kg
