Question

isabel 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?

Explanation:

Step1: Calculate the area of the rectangular garden

The formula for the area of a rectangle is \( A = length \times width \). Given that the length is 15 feet and the width is 12 feet, we substitute these values into the formula:
\( A = 15 \times 12 \)
\( A = 180 \) square feet.

Step2: Determine the number of fertilizer bags needed

To find the number of bags, we divide the total area of the garden by the area covered by each bag. Each bag covers 20 square feet, so we calculate:
\( \text{Number of bags} = \frac{180}{20} \)
\( \text{Number of bags} = 9 \)

Answer:

9
