This problem is from BL’s Math Games.

“What’s the area of the red triangle?”

BL decided to see what kind of solution ChatGPT would come up with.  After several tries and prompts it seemed to oblige.  I don’t know what BL’s prompts were, and in the statement of the problem outside the subscription wall he never explicitly says what the problem is, namely, to find the area of the red triangle.

There also seems to be some ambiguity about the constraints on the problem, that is, how much of the appearance of the diagram should the solver assume?
