The area of a square is given by the equation \"A+=+s%5E2\" where 's' is the length of the side.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So if \"A=81\", then \"81=s%5E2\", which means that \"s=sqrt%2881%29=9\". So \"s=9\" telling us that the length of the side is 9 units.

\n" );
