If they Google NaN they can see what the answer means.
If it can display" no solutions" in their language too, that is a bonus - it explains why the answer is Nan, not just what the answer is.

At the top it says "No solution with given data" which seems pretty clear to me. Leaving S= blank is consistent with leaving all the other fields blank. If you're going to put NaN on S, then it seems like NaN should go on all of the blank fields.

You could just as well have "S=imaginary" with the idea that students might be motivated to Google that as well. There's a place for prompting students to look up topics, but I don't think the Triangle Solver App is it. Just my opinion of course.
