For a triangle,
\n" ); document.write( "\"A=%281%2F2%29bh\"
\n" ); document.write( "\"%281%2F2%29b%28b-3%29=20\"
\n" ); document.write( "\"b%28b-3%29=40\"
\n" ); document.write( "\"b%5E2-3b=40\"
\n" ); document.write( "\"b%5E2-3b-40=0\"
\n" ); document.write( "\"%28b-8%29%28b%2B5%29=0\"
\n" ); document.write( "Only positive solution works here,
\n" ); document.write( "\"b-8=0\"
\n" ); document.write( "\"b=8\"
\n" ); document.write( "Then,
\n" ); document.write( "\"h=8-3\"
\n" ); document.write( "\"h=5\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
