1. Molina is sewing a border of ribbon onto her rectangular picnic blanket. The long side of the blanket is 7 feet and the short side is 4 feet. How many feet of ribbon will she need?

She will need 22 feet of ribbon

Step-by-step explanation:

The length of the border of ribbon is equal to the perimeter of the rectangular picnic blanket

The formula of the perimeter of a rectangle is P = 2(l + w), where l is its length and w is its width

∵ The long side of the blanket is 7 feet

∴ l = 7

∵ The short side of it is 4 feet

∴ w = 4

Use the formula of the perimeter above to find the perimeter of the blanket

∵ P = 2(l + w)

∴ P = 2(7 + 4)

- Add the numbers in the bracket

∴ P = 2(11)

∴ P = 22 feet

∵ The length of the border of ribbon is equal to the perimeter

    of the blanket

∴ The length of the ribbon is 22 feet

∴ She will need 22 feet of ribbon
