\documentclass[tikz]{standalone}
\begin{document}
\begin{tikzpicture}[scale=2] % <--- scale goes HERE!
    \begin{scope}[line width=2pt]
        \foreach \x in {0,1,...,10} {
            \foreach \y in {0,1,...,3} {
                \draw (\x*0.2,\y*0.2) rectangle +(0.2,0.2);
            }
        }
        \node[right] at (11*0.2,2*0.2) {2 squares};
        \node (a1) at (9*0.2+0.1,0*0.2) {};
    \end{scope}
    \begin{scope}[ultra thick,yshift=-1.2cm]
