The diagonals of the square with vertices at (0,0), (0,4), (4,0), and (4,4) meet at point P. What are the coordinates of P

Question

This is on my math assignment and i have no idea how to figure it out 

Answer 1

Do you know the distance formula? The diagonals meet halfway between themselves, which should also be the center of the square, or (2,2).
