Question

bod 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 area of rectangle

The area \( A \) of a rectangle is given by the formula \( A = \text{length} \times \text{width} \). Here, length \( l = 15 \) feet and width \( w = 12 \) feet. So, \( A = 15 \times 12 \).
\( 15\times12 = 180 \) square feet.

Step2: Find number of fertilizer bags

Each bag covers 20 square feet. Let the number of bags be \( n \). Then \( n=\frac{\text{Total Area}}{\text{Area per bag}}=\frac{180}{20} \).
\( \frac{180}{20}=9 \).

Answer:

9
