Answer:

15 inches of ribbon is needed.

Step-by-step explanation:

To find how much ribbon is needed to go around the edge of the card, find the perimeter. The perimeter is the length around the card.

Perimeter is found by P = 2l + 2w where w=3.5 and l=4.

P = 2(4) + 2(3.5)

P = 8 + 7

P = 15 inches
