Question

The farmer needs to buy fertilizer to spread on his garden. The garden is a 20 x 15 rectangle. A bag of fertilizer covers 30 ft.² of garden. How many bags of fertilizer will be needed?

Answer 1

Answer:

$10$

Step-by-step explanation:

The area of a rectangle is given by $A=lw$, where $l$ is the length of the rectangle and $w$ is the width of the rectangle. Therefore, the area of a 20 x 15 rectangle is equal to $20\cdot 15=300\:\mathrm{ft^2}$.

Since one bag of fertilizer covers 30 square feet, the farmer needs $\left \lceil \frac{300}{30}\right \rceil=\boxed{10}$ bags of fertilizer.

Answer 2

Answer:

10 bags of fertilizer.

Step-by-step explanation:

300 area

300 / 30 = 10 bags
