Take a five inch square and cut off the seam allowance all around. Now you have a 4.5 inch square. Cut that 4.4 inch square into three equal blocks each way. 4.5 divided by 3 = 1.5.
This is your finished size. Then you add half an inch to that measurement to get the measurement of each square in the nine patch. You need 2 inch squares to start with.
Quite a few of you got it right.
