Question

lisa 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 garden

The area of a rectangle is \(A = length\times width\). Given \(length = 12\) feet and \(width = 10\) feet, so \(A=12\times10 = 120\) square feet.

Step2: Determine the number of fertilizer bags

If each bag covers \(30\) square feet, then the number of bags \(n=\frac{Area\ of\ garden}{Area\ per\ bag}\). Substitute \(A = 120\) and \(Area\ per\ bag=30\), we get \(n=\frac{120}{30}=4\).

Answer:

\(4\)
