Or perhaps the words "Area" and "no solution" were intentionally not used so as to avoid the need for translations. If so, then leaving it blank would be better than NaN.

If NaN is displayed as "blank" , how would your students Google "blank" to find out what the answer means, and why it is there?
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.

I really like NaN plus "No solutions" if possible.

Googling NaN opens a door into the wide world of IEEE Floating Point, from there to floating point representations in general, and from there in to Applied Numerics. You might inspire somebody to dig more deeply. And even if you don't, it gives you the opportunity to explain that floating point numbers in a machine are different from the continuum of Real numbers in pure mathematics... i.e. explain a little of what NaN's really are, and why they exist.

Just my $0.02 worth.
