I'm glad to have been able to help you with this. It's an interesting
problem, and one that has been around (in various forms) for a very
long time. I remember having encountered a similar problem in the
1960s. I believe it may have been in Martin Gardner's column in
"Scientific American." Online, the problem is sometimes called
"Simeon's Triangle."

For the record, here's an explanation:

Yup - it's simply the fact that there IS NO 13x5 triangle.  There is a
2x5 and a 3x8, but they are NOT similar triangles, and they do NOT fit
together to make a 13x5.

Wow, that one stumped me too.
