1
00:00:00,937 --> 00:00:07,644
At Level 2, each segment is one third (1/3) the length of the segments at Level 1.
2
00:00:07,644 --> 00:00:12,826
So it's one third of L (L/3) over three ((L/3)/3), which is L over nine (L/9),
3
00:00:12,826 --> 00:00:15,749
and you can see there are sixteen (16) segments.
4
00:00:15,749 --> 00:00:20,324
That is four (4) times the number at Level 1.
5
00:00:20,324 --> 00:00:26,708
And so L over nine (L/9) times sixteen ((L/9) x 16) is (16/9)L,
6
00:00:26,708 --> 00:00:30,708
so the answer is "D."
