So, let's let w be the length of the first piece of the board.
(I was going to do l (small L) but it's too hard to see on computers)
second piece is 2w since it's twice the length of first.
third piece is 6w, since it's six times longer than the first.
and these three pieces were one one 180ft board, therefore, that means:
w + 2w + 6w = 180
now let's solve for w (length of first piece)!
w + 2w + 6w = 180
7w = 180
w = 180/7 ≈ 25.71ft
Therefore, the first piece of the board would be approximately 25.71ft.

Now we know that 
Answer:
do you mean height, because then the answer would be a length of 9 and height of 6
Step-by-step explanation:
9+9=18
6+6=12
18+12=30
