That's a really interesting problem. Even though you have enough area with the two 10" squares, it's hard to figure out. If you cut each into 4 squares that are 5" each, you still wouldn't have enough for a nine patch. You'd only have eight squares.
If you cut each into thirds, you'd have 18 squares that are about 3 1/3" square. From 15 of those you could sew a block that's 5 x 5, which would turn out to be about 11 1/3" square. I think you'd have to cut them so that you could use the maximum number of the squares that you cut.
Very interesting...
