There are many methods in solving this, but I recommend this formula:
\n" ); document.write( "A=s^2((sqrt of 3)/4)
\n" ); document.write( "Substitute:
\n" ); document.write( "A=(18)^2 ((sqrt of 3)/4)
\n" ); document.write( "A=324(sqrt of 3)/4
\n" ); document.write( "simplify: 324/4
\n" ); document.write( "81 sqrt of 3 dm^2 is the answer or if you want a more precise answer:
\n" ); document.write( "140.296115413dm^2\r
\n" ); document.write( "\n" ); document.write( ":)
