The rectangle, dimensions x and 9. Perimeter would be \"2x%2B2%2A9=2x%2B18\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The rectangle's width is x while its length is 9.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The square uses side length x also, and perimeter is \"4x=20\"; meaning \"highlight%28x=5%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Back to perimeter of the rectangle,
\n" ); document.write( "\"2%2Ax%2B18\"
\n" ); document.write( "\"2%2A5%2B18\"
\n" ); document.write( "\"10%2B18\"
\n" ); document.write( "\"highlight%2828%29\", the perimeter of the rectangle.
\n" ); document.write( "
\n" );
