Question 180869
I have 60 inches of width and have 48 inches of height in my entertainment center. I am going HDTV shopping, what is the biggest diagonal TV that I can get?
-----------------------
{{{d^2 = 60^2 + 48^2}}}
{{{d^2 = 5904}}}
{{{d = sqrt(5904)}}}
d = ~76.8 inches (the outside of the TV, not the screen)
And, TVs are not square.  If you take into account they have an aspect ratio of 16:9, it will affect the answer.
