a^2+b^2=c^2
9.5^2+5^2=c^2
90.25+25=115.25
sq rt 115.2=10.7 cm

The problem is, you either have an object that doesn't actually have a right angle, and therefore the Pythagorean Theorem doesn't apply (highly unlikely, I think) or you just didn't measure very carefully.

Here's the problem. and . Add them up and you get but . So, redo your measurements and then put the new numbers in to the calculations I just showed you. You'll never get it perfect, but you should, with due care, be able to improve on your measurement error.

My calculator said it, I believe it, that settles it
