I got 10 - I just counted the units diagonally. :P
I could definitely be wrong. What kind of class is this? Geometry or Algebra?

- leonardo0430

geometry

That's a heck of a formula. I'm in geometry and they haven't given me formulas like that quite yet o.o

12.8 is the distance between the high school and the library. The question however asks for the distance between Tina's home and the HS.
Note that it's given that Tina live exactly between the HS and the library.

The formula is called 'the distance formula' and is basically the Pythagorean theorem.
