\n" ); document.write( "\n" ); document.write( "The doorway of a family room is in shape of rectangle, so diagonal will divide it in two right triangles.\r
\n" ); document.write( "\n" ); document.write( "use Pythagorean theorem:\r
\n" ); document.write( "\n" ); document.write( "\"d%5E2=78%5E2%2B36%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"d%5E2=6084%2B1296\"\r
\n" ); document.write( "\n" ); document.write( "\"d%5E2=7380\"\r
\n" ); document.write( "\n" ); document.write( "\"d=sqrt%287380%29\"\r
