I have another Pythagorean theorem: word problem that has stumped me for the last time. The floor of storage unit is 12 meters long and 9 meters wide. What is the distance between two opposite corners of the floor? Thank you so much!

Answer 1

So you just want the hypotenuse of a triangle with sides 12 and 9, so
h^2 = 12^2 + 9^2 = 225
take √225 and you have it.

(after doing about 5000 of these, you will recognize the simplest right-angled triangle
of 3-4-5 units has been multiplied by 3 to get yours)

Answer 2

Thank you so much. Now I see what I did wrong. I'm such an idiot.
