13. Find the side and diagonals of the square

The points \(A(7, 12)\), \(B(17, 12)\), \(C(17,22)\) and \(D(7,22)\) in order are the vertices of a square. Find the value of distance and diagonals of the square.

 

The distance between the points is  and the diagonal is √198√200√199√203 this is equal to all the points which make the square shape.
