vampirchik [111]

Answer:

<u>If Caeli  will use all of the fabric she has, the base of the flag should be of 4 feet.</u>

Step-by-step explanation:

1. Let's review the information provided to answer the question correctly:

Area of the fabric Caeli  has and want to use and design = 10 square feet

Height of the rectangle of the rectangle shape = 2.5 feet

2.  What is the base of the flag if she will use all of the fabric she has?

Area of the shape of the rectangle = Height of the flag * Base of the flag

Replacing with the real values:

10 square feet = 2.5 feet * Base of the flag

10 square feet/2.5 feet = Base of the flag

<u>Base of the flag = 4 feet</u>

<u>If Caeli will use all of the fabric she has, the base of the flag should be of 4 feet.</u>
