random rectangular sizes

Hi.

Im fairly new to grasshopper but I have a specific task and I need some help.

I want to create smaller randomly sized rectangles (with a specific set of dimension variables) that would fill up a bigger rectangle with minimum and maximum dimensions and area in a given surface. How can I set this up.

Precisely... a

2.0m x 9.0m rectangle to be divided into smaller ones with the following dimensions:

0.3m, 0.4m, 0.5m, 0.6m, 0.8m. And I need to specify that if the area would be smaller or bigger than a specific size, it won't return a rectangle.

Many thanks!
