Sharon has a rectangular bedspread that measures 3 feet by 5 feet. She wants to
sew a fringe around the edge of the bedspread.
What length of fringe does Sharon need to purchase?
feet
Sharon gets a new bedspread that is 1.25 feet longer.
What length of fringe does Sharon need for the longer bedspread?
feet

The length of fringe Sharon needs to purchase is: 16 feet

If Sharon gets a new bedsheet of 1.25 feet longer, she will need a new length of fringe of: 18.5 feet

Recall:

Perimeter of a rectangular = 2(length + width)

Given the following:

The length of fringe Sharon will need to purchase = perimeter of Sharon's rectangular bedspread

Perimeter = 2(3 + 5) = 16 feet

For a new bedspread that is 1.25 feet longer, she would get the following length of fringe:

Length = 3 + 1.25 = 4.25 feet

Width = 5 feet

New Perimeter = 2(4.25 + 5) = 18.5 feet
