Answer:
The length of the longer piece is 180.
Step-by-step explanation:
If one piece is 3 times the other piece than their are 4 pieces. So, divide 240 by 4 to get 60. Since it is 3 times you multiply the 60 by 3 to get 180. Thus, the small piece is 60 and the large piece is 180. 180 is 3 times as long as 60 and 60 + 180 = 240.
