Because the gap between each row is different, you can't form a square, you have to count it yourself.

There are 6 people in each row, 7 people in the upper row and 5 people in the lower row.

Because it is a computer, there are some errors. Please draw it on the paper according to the above method.

Pay attention when drawing: the left and right lines are on the upper line and the lower line is on the left and right lines. (Draw the top line first)
