notice the units are different. this is an easy fix. either divide the inches by 12 or multiply the ft by 12. (12 inches in a foot)
tv= 31in x 57in= 1,767 in2
wall= 8ftx9ft= 72 ft2
if the wall is 72ft2, then it would be 864in2
(72in2 x 12= 864in2)
if the tv is 1,767 in2 and the wall is 864in2 ; the tv would actually be too big for the wall; or cover all of that wall and then some.
