Patterned shading parts of a rectangle

Question

Normally I try to have a skeleton at least before I ask a question, but this time I don't know where to begin, so my apologies for asking a cold question. I am trying to get parts of a rectangle hatched as shown in the figure below, but don't know how to begin. Any help would be much appreciated.

There are many ways to do this. For example draw overlapping rectangles and shade then appropriately:

\documentclass{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
    \filldraw[fill=white, draw=black] (0,0) rectangle (8,1);
    \filldraw[fill=green, draw=black] (0,0) rectangle (2,1);

    \filldraw[fill=white, draw=black] (0,-2) rectangle (8,-1);
    \filldraw[fill=green, draw=black] (0,-2) rectangle (2,-1);
    \filldraw[fill=green, draw=black] (4,-2) rectangle (6,-1);
\end{tikzpicture}
\end{document}

If you are only going to draw simple rectangles then you can also try using tabular along with cellcolor command from xcolor package. For example:

\documentclass{article}
\usepackage[table]{xcolor}
\begin{document}
\begin{tabular}{*4{|p{2em}}|}
\hline
    \cellcolor{green} & \multicolumn{3}{p{6em}|}{}\\
\hline
    \multicolumn{4}{c}{} \\ 
\hline
    \cellcolor{green} & & \cellcolor{green} & \\ 
\hline
\end{tabular}
\end{document}
