Answer:
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
