If you've tried something and it doesn't work, post some code for us to look at...

Well, the second explanation was at least a more precise specification.
So you will have a sketch with a button taken somewhere, able to do something when clicking on it; and a rectangle.
You should parametrize the rectangle's height with a global variable, ie. defined outside of setup() and draw().
In draw(), you call background() to erase the previous rectangle, and draw the shape, using this global height.
When user clicks on the button, you increase the height, which will be use automatically in draw().
I hope I am clear enough; I don't want to give whole code, as it looks like homework.
