To find the area you need to compute the height using Pythagorean Theorem:\r
\n" ); document.write( "\n" ); document.write( "\"h=sqrt%2812%5E2-6%5E2%29=sqrt%28108%29=6sqrt%283%29\". Now we find the area\r
\n" ); document.write( "\n" ); document.write( "\"A=%281%2F2%29%2A12%2A6sqrt%283%29=36sqrt%283%29+cm%5E2\"
\n" ); document.write( "
\n" );
