Final answer:
The student will need 7 bags of fertilizer to cover his garden.
Step-by-step explanation:
To find out how many bags of fertilizer Deon will need to cover his garden, we need to calculate the area of the garden first. The area of a rectangle is found by multiplying its length by its width. So, the area of Deon's garden is 14 feet × 11 feet = 154 square feet. Now, we need to divide the area of the garden by the area covered by each bag of fertilizer. Since each bag covers 22 square feet, we divide 154 square feet by 22 square feet per bag. The result is 7 bags, so Deon will need 7 bags of fertilizer to cover his garden.
