Answer:
The answer is 12 bags
Step-by-step explanation:
This is because the first big rectangle is 48 feet while the smaller one is 12 feet. By adding them together you get 60. 60 divided by 5 is 12 so its 12 bags.
12 bags
12 x 4 = 48
2 x 6 = 12
48 + 12 = 60
60ft² is the area of the garden.
60 ÷ 5 = 12
12 bags are needed
