Can 20 squares fit in a square array?
Yes. And here is an example: Draw a 6*6 array, put the two 3*3 squares anywhere within that aray so that they don't overlap. That leaves 18 square units - each one to be occupied by one of 18 unit squares. 2 large (3*3) squares plus 18 small (1*1) squares makes 20 squares Total area = 6*6 square array DONE!
