1. The length of ribbon available is 46 feet. The banner has a length of 15 feet and an unknown width. The ribbon goes around the outside of the banner. Write an expression to describe the length of ribbon that will be needed. Remember, the perimeter of a rectangle is twice the length plus twice the width. Use w to represent the width.

for question 1. I got   p=2(15+w)

2. The length of ribbon available is 46 feet. Write an inequality that compares your expression from part 1 with the length of ribbon available.

for question 2. I got p=2(15+w)≤46

3. Use the inequality from part 2 to solve for the width of the banner.


4.Write your answer in a sentence.

1.       I got the same answer as yours:

P = 2 (15 + w)

2.       I also got the same as yours:

P = 2 (15 + w) ≤46

3.       To solve for the width we have to leave the w to the left side alone like this:

15 + w ≤ 46/2

W ≤ 23-15

W ≤ 8 feet

4.       The width of the banner is less than or equal to 8 feet.
