You can put this solution on YOUR website!
replace the factors with what you know.
\n" ); document.write( "A=bh(1/2)
\n" ); document.write( "81=b(9)(1/2)
\n" ); document.write( "divide both sides by nine
\n" ); document.write( "9=b(1/2)
\n" ); document.write( "multiply both sides by 2 two get rid of hte 1/2
\n" ); document.write( "18=base
\n" ); document.write( "
\n" );
