or you may want to write a small python or perl script to create your
rectangles in a text file with WKT that you can load with the delimited
text loader plugin.
My "non-coding" workflow with QGIS 2.2 would be:
- install improved polygon capturing plugin
- create a new line vector layer as a helper line.
- activate the layer for editing and click the new icon (tool tip says
"CAD-like improved line capture").
beneath your TOC is a new window with a distance and an angle field.
Pick your starting point, then set the distance to 9000 and lock the
field. Search the right direction and Left-Click for the first segment.
Change distance to 1000 and angle to -90 and lock that too. Left-Click.
Change distance to 9000 leave angle at -90. Right-Click to stop
digitizing.
Now you have three line segments, one 9km, another 1km, and the next
parallel to the first with 9km as well.
Save edits! (You could also use a polygon layer for this construction ...
same workflow).
- Activate the toolbox and search for "densify".
Pick "Densify geometries given an interval".
Choose your helper line and insert 1000 as interval.
You now have a temporal "densified layer" with vertices every 1000m,
which you can see when you toggle editing or change the layer style to
markerline -> on each vertex.
- activate the densified layer in the snapping options (to vertex and some
100 meters according to your scale).
- create your final polygon layer and start to digitize your squares
snapping to the vertices of your densified layer.
OK, this might take some minutes, but definitely less time than learning
python like Andreas suggested ;) (but in long run he might be right)

There is so many options with FOSSGIS - you just have to find out what
suits you best.

If you still would prefer do it manually, please take a look into
Improved

So far I know only the corresponding functions in ArcMap from ESRI.
QGis
seems equipped in the basic version with less features.
If you look carefully you see that qgis has many features that in
ArcGIS
are only available in (very well) payed extentions. You just need to
know
where to find them.
Although I have the
plugin " Rectangles ovals digitizing " installed, but can not choose
here
the edge length . In addition, the following square is to connect
seamlessly
For me, the fastest way to do this would be to use Andreas suggestion,
the
Vector Grid, to create the the necessary number of squares (Polygons),
say
18 x 2.
Like Andre said, they will be aligned with the coordinate system and
not
with your working area. But that is not a problem, cause you can edit
the
layer, select the desired squares, and use Rotate feature and move
feature
in the digitizing toolbar to align and put the squares over your
working
area.
