By nodes I just meant corners: places where the lines intersect.

(In graph theory, those points are called nodes, and lines that connect them are called edges.)

 

I meant i didn't understand how you found out the answer using the number of nodes.How did you find the rectangles that are combinations of two or more rectangles using the number of nodes?Is there some formula or you just simply counted them?

 

Just counted them.

Using nodes just put them into piles sort of. A convenient way to keep track.

Well, that's a good method bcoz after counting a few i forget which ones i counted. that's why i decided to draw them out.
