If a square has an area of 90, then each of its sides is the square root of 90, because Area of a square=s*s where s is the length of a side.
\n" ); document.write( " $\"sqrt%2890%29=3sqrt%2810%29\"$
\n" ); document.write( "So the fencing needed to enclosed it is the perimeter of the square, which would be 4 times the side length.
\n" ); document.write( " $\"4%2A3sqrt%2810%29=12sqrt%2810%29\"$ \n" ); document.write( "

\n" );
