Answer:
14 feet
Step-by-step explanation:
Let the shorter piece have length x.
Since the ratio is 2:3 and the longer piece is 21 feet long, we can write that as 2:3 = x:21.
Writing it as fractions, we get 2/3 = x/21 —(multiply by 21)—> x = 21*2/3 = 7*2 = 14 feet.
Thus, the shorter piece is 14 feet.
