let x=width, so 2x=length\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "area = area __ (x+3)(2x+3) = (x)(2x) + 54\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x^2+9x+9 = 2x^2+54\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "subtracting 2x^2+9 __ 9x = 45\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "dividing by 9 __ x = 5
