A. 2 feet long
B. 26 inches long
C. 22 inches long
D. 1 1/2 feet long

Answer 1

A. 2 feet long

Explanation:

the weight starts at 0.5 lbs = 10 inches, and after that every extra 0.5 lb means it's 2 inches longer. so the last data point we have is 2.5 lbs = 18 in, so we can assume that 3.0 lbs = 20 in, 3.5 lbs = 22 in, and 4.0 lbs = 24 in, and 24 inches is equal to 2 feet
