Area is \"%281%2F2%29bh\" and \"b=40-h\".
\n" ); document.write( "\"A=%281%2F2%29%2840-h%29h\"

\n" ); document.write( "\"A=20h-%281%2F2%29h%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Finding maximum A,
\n" ); document.write( "\"dA%2Fdh=20-h=0\"
\n" ); document.write( "\"h=20\"-----------height for maximum A.\r
