Minimal example:

\documentclass{memoir} \usepackage[utf8]{inputenc} \thispagestyle{empty} \begin{document} \begingroup \color{blue} \rule{\paperwidth}{7.5cm} \endgroup \end{document} 

I just want to make a box which is blue, has paperwidth and is placed at the bottom and is 7.5cm high. How to do that?

Thank you very much in advance :)

PS! It would be nice if I also could write a text which begins 7 cm from the right edge and goes to maximum 2 cm of the right edge and starts two centimeters under the blue beginning and ends to cm before bottom (white text) :D

And a picture which is 2 cms from each edge of the paper (also in the blue box) and is 9 cm long.
