For a triangle,
\n" ); document.write( " $\"A=%281%2F2%29bh\"$
\n" ); document.write( " $\"18=%281%2F2%29b%284b%29\"$
\n" ); document.write( " $\"b%5E2=9\"$
\n" ); document.write( " $\"b=3\"$ $\"m\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"h=4%283%29\"$
\n" ); document.write( " $\"h=12\"$ $\"m\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
