The Folding Ruler (Posted on 2024-06-27) Difficulty: 3 of 5
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.

What is the smallest possible length of the ruler? What if the second triangle has 3 times the area?

Assuming that integer areas are required:

What is the smallest possible length of the ruler? 16 feet, corresponding to triangles  {3,4,5} and {5,5,6}.

What if the second triangle has 3 times the area? {5,5,6} and {9,10,17} for a 12-yard ruler.
