I already answered this for you. Why did you change your answer?
Not so. Think about your answer. 9+12=21
Those cannot be the sides of a triangle. The 9 and 12 sides would have to lie completely flat on top of the 21 side.
The third side must be less than 9+12. In fact, if the 3rd sides is x,
12-9 < x < 12+9

12-9 < x < 12+9
Use the Pythagorean theorem, which is: a squared + b squared = c squared
So that is 12x12 + 9x9 = c x c
or 144 + 81 = c x c
to solve add 144+81= 225
Take the square root of 225 which equals 15
Your answer is the diagonal (or hypotenuse) equals 15

Oh, by the way, Steve?
You're a moron, don't attempt to help if you're clueless.
I realize of course Pear, that this doesn't help you, hopefully it will help someone else.
