I interpret the problem like this
\n" ); document.write( " The length of the rectangle is \"4x\" and the width is \"2x\" .
\n" ); document.write( "That makes the area
\n" ); document.write( "\"area=%284x%29%2A%282x%29=8x%5E2\" and the perimeter would be
\n" ); document.write( "\"perimeter=2%2A%284x%2B2x%29=2%2A%286x%29=12x\"
\n" ); document.write( "
\n" );
