Question

yolanda is fertilizing her garden. the garden is in the shape of a rectangle. its length is 12 feet and its width is 10 feet. suppose each bag of fertilizer covers 30 square feet. how many bags will she need to cover the garden?

Explanation:

Step1: Calculate the area of the rectangle

The formula for the area of a rectangle is \(A = l\times w\), where \(l = 12\) feet (length) and \(w = 10\) feet (width).
\(A=12\times10 = 120\) square feet.

Step2: Determine the number of fertilizer bags

Divide the total area \(A\) by the area covered by each bag. Each bag covers \(30\) square feet. So, the number of bags \(n=\frac{A}{30}\).
Substitute \(A = 120\) into the formula: \(n=\frac{120}{30}=4\).

Answer:

\(4\)
