Answer:
3.5 feet
Explanation:
You want to know the tail length of an alligator whose body length is 7.7 feet, if tail length is proportional to body length, and an alligator with a body length of 4.4 feet has a 2 ft tail.
Proportion
The proportion can be written ...
tail/body = x/(7.7 ft) = (2 ft)/(4.4 ft)
Multiplying by 7.7 ft gives ...
x = (7.7 ft)(2/4.4) = 7/2 ft = 3.5 ft
The tail length is 3.5 feet.
