Call the shorter piece x
The longer piece is 3x
given:
x+%2B+3x+=+240
4x+=+240
x+=+60
3x+=+180
The pieces are 60 in and 180 in long

let one piece be x and another one y

240in+=x%2By
since one piece is three times the length of the other, we have
x=3y..substitute in 240in=x%2By and find y
240in=3y%2By
240in=4y
240in%2F4=y
60in=y

now find x
x=3y
x=3%2A60in
x=180in

the lengths of the pieces: 60in and 180in
