Answer:
7.5 feet long
Step-by-step explanation:
if I had one, 5 foot sandwich, I would have 8 pounds. if I had 2.5 more foot of sandwich I would have 4 more pounds ( because 2.5 feet is half of 5 feet which means we would have to divide 8 pounds by 2). which means I have 8 pounds and 4 pounds, which equals 12 pounds. I also have 5 feet and 2.5 feet of sandwich which is equal to 7.5 feet. since it's asking the length of a 12 pound sandwich, your answer is 7.5 feet long.
