Alex owns one of those folding rulers where each segment is exactly 1 foot long. While playing with the open ruler he formed it into a triangle. Then he refolded it into a second triangle with double the area. Next he refolded it into a third triangle with triple the area.
What is the smallest possible length of the ruler?

The program did not allow for rounding error in doing comparisons. The following two lines were left out as a result, both in the triple area:
3.992179855667828 11.976539567003485 1 8 8 4 6 7 17
9.921567416492215 29.764702249476645 2 11 12 8 8 9 25
This does not affect the answer as 17- and 25- foot rulers do not occur in the double area.
