\n" ); document.write( "width of rectangle A = x/5
\n" ); document.write( "height of rectangle A = 20
\n" ); document.write( "..
\n" ); document.write( "Area of rectangle A = 4x
\n" ); document.write( "..
\n" ); document.write( "Area of rectangle A = 6 times area of rectangle B
\n" ); document.write( "..
\n" ); document.write( "Area of rectangle B = 2x/3
