Before change, $\"x=y\"$ , and area is $\"xy\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "After change, $\"x%2F2\"$ and $\"k%2Ay\"$ are the new values for the sides and this is now a rectangle. k is a factor applying to y.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"xy=%28x%2F2%29%28ky%29\"$
\n" ); document.write( " $\"xy=xy%281%2F2%29k\"$
\n" ); document.write( " $\"k=2\"$ \n" ); document.write( "
