The highlight%28D%29iagonal, the highlight%28H%29eight, and the highlight%28W%29idth form a Right Triangle. And we all know in a Right riangle, the 3 sides are in a relation into equation:
hyp%5E2=opp%5E2%2Badj%5E2
where-----system%28hyp=D=32inches%2Copp=H=16inches%2Cadj=W=unknown%29
Then:
D%5E2=H%5E2%2BW%5E2
32%5E2=16%5E2%2BW%5E2
W%5E2=1024-254=768
W=sqrt%28768%29=27.7inches, ANSWER
