Yes.. the squares for the 9 patch should be 4.5" each.. the solid triangles should be 12 5/8" squares cut in 1/2 from corner to corner for the side blocks. I don't have the corner triangles figured yet. will let you know about those. I'm thinking you would cut a 13" block then cut corner to corner both directions to make those.. but I need to "prove" that out.
