\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There are two choices.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The two equal legs are each 13 feet, and the triangle's area is $\"%281%2F2%29%2A13%2A13=169%2F2\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "OR\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The long side, hypotenuse, is 13 feet, making each congruent leg $\"13%2Asqrt%282%29%2F2\"$ ; and then the triangle's area is $\"%281%2F2%29%2813sqrt%282%29%2F2%29%2813sqrt%282%29%2F2%29=highlight_green%28169%2F4%29\"$ .
\n" ); document.write( "If your description intends to mean, one and only one side is 13 feet, then this one is the area you want. \n" ); document.write( "

\n" );
