You can put this solution on YOUR website!
The measurement of a TV is usually done diagonally. Therefore, the width, length, and the diagonal forms a \"right triangle\". You can now apply Pythagorean theorem to solve your problem.

\n" ); document.write( "30^2 = 24^2 + h^2
\n" ); document.write( "30^2 = 24^2 + h^2
\n" ); document.write( "900 = 576 + h^2
\n" ); document.write( "324 = h^2
\n" ); document.write( "18 inches = h (height of TV)
