Question
Lisa is fertilizing her garden. The garden is in the shape of a rectangle. Its length is 15 feet and its width is 12 feet. Suppose each bag of fertilizer covers 20 square feet. How many bags will she need to cover the garden?bags
Solution
To solve this problem, we need to follow these steps:
-
First, we need to find the area of the garden. The area of a rectangle is calculated by multiplying its length by its width. So, the area of the garden is 15 feet * 12 feet = 180 square feet.
-
Next, we need to determine how many bags of fertilizer Lisa needs. Each bag covers 20 square feet, so we divide the total area of the garden by the area that one bag can cover. So, 180 square feet / 20 square feet/bag = 9 bags.
Therefore, Lisa will need 9 bags of fertilizer to cover her garden.
