As you're looking for a square, this means that the two sets of coordinates have to be the same ( meaning that the two coordinates at the top and the bottom of the square have to be the same, eg 4 and 4 and 9 and 9). This means that one of this square will be 8 and 8, and 3 and 3 (as you've got one three, so the other one must be the same). The same rule applies to the sides of the square. In this case, you've got 2 and 2 and 7, therefore, meaning that the other side has to be 7. As you've got a square, this means that they must be two sets of opposite coordinates. Therefore, the missing coordinate that you are looking for is (3,7) Hope this helps :)
The answer is (3,7) for the last coordinates
The missing coordinate of the square is (3, 7). This was determined by matching the given coordinates of the square with the properties of a square where opposite sides are parallel. Hence, we used the coordinates of the known points to find the unknown one.
