Step-by-step explanation:

Gracie wants to create a rectangular-shaped garden in her backyard. The formula for determining the area of a rectangle is expressed as

Area = 20 × 16 = 320 ft²

If one bag of fertilizer only covers an area of 15ft², it means that the number of bags of fertilizer gracie will need for her garden is

320/15 = 21.33 bags
