Danny has a rectangular rose garden that measures 8m by 12.5m. One bag of fertilizer can cover 16m2. How many bags will he need to cover the entire garden?

we will need 7 bags

Step-by-step explanation:

To solve this problem we first have to calculate the total area of the garden

a = area

b = base = 8m

h = height = 12.5m

a = b * h

we replace with the known values

a = 8m * 12.5m

a = 100m²

Now that we know the total area of the garden and the area occupied by a single bag, we divide the total area by what a bag covers.

100m² / 16m² = 6.25 bags

because we cannot buy a fraction of a bag we will need 7 bags
