[QUESTION] How to define a shapes limit?

[eemmy]

Hello, I was wondering if there is a way to add a size limit to the area that will be generated, for example, if I need to calculate the arrangement of squares within a larger area as a certain size, how would I limit this? And if it is possible, would it generate only for the shapes that fit inside or would it pass a parameter informing whether it was used or not?

Thanks in advance and sorry for the bad English.
