Question

omar is fertilizing his 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 he need to cover the garden?

Explanation:

Step1: Calculate garden area

The area formula for a rectangle is $A = l\times w$, where $l = 15$ feet and $w = 12$ feet. So $A=15\times12 = 180$ square - feet.

Step2: Calculate number of bags

Let the number of bags be $n$. We know that each bag covers 20 square - feet. So $n=\frac{A}{20}=\frac{180}{20}=9$.

Answer:

9
