You are right!
Ok, that was a little more elegant
well that tutor does this for a living. Ofc her solutions are elegant haha

to be fair, we spend a lot of time studying haha
I'm impressed by that reasoning. I think I would have tried to calculate the meeting point.
same here. I was stumped tbh.
I have to unlearn and relearn my Maths in order to prepare my children for the current realities of the Maths syllabus
based on what?
Don't know. I'd probably try to logic that out, and if not possible eventually maybe realize the trick.
In other words, I'd waste a lot of time brute forcing it before I'd stumble upon a more elegant solution.
That’s what I started doing. Once I had it sketched out and parameterized, I realized that the intersection point could be anywhere in the middle box.
Ah, I thought you took one look, saw that you weren't given enough information for the intersection, and reasoned the intersection could be anywhere, including on a straight line between the two corners.
I did start out with an inclination that there was a cute simple answer like that, but I started working it out to make sure I wasn’t missing something.
Since we aren’t told anything about where the triangles meet, it must not matter.
So, we can do the calculation for two triangles that meet at one of the box corners.
That yields 28.
