Answer:
The first thing to do is to calculate the area of the lawn:
The problem tells us that each bag of seed covers 5000 square feet, so if the landscaper bought 2 bags he can cover 10000 square feet, then the landscaper with the two bags of seed can cover the 8000 square feet of grass only once. As he only has enough seed left over to cover 2000 square feet of grass, he does not have enough left to cover the lawn
area of law = 200×40
8000ft^2
