\n" ); document.write( "---
\n" ); document.write( "width = 16x
\n" ); document.write( "height = 9.1x
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "(16x)^2 + (9.1x)^2 = 40^2
\n" ); document.write( "------
\n" ); document.write( "(16^2+9.1^2)x^2 = 1600
\n" ); document.write( "x^2 = 4.722
\n" ); document.write( "x = 2.7131
\n" ); document.write( "---
\n" ); document.write( "width = 16*2.7131 = 43.41 inches
