Coordinates of the intersection of the diagonals

In the rectangular coordinate system, a rectangle ABCD is drawn. The vertices of the rectangle are determined by these coordinates
A = (2.2)
B = (8.2)
C = (8.6)
D = (2.6)

Find the coordinates of the intersection of the diagonals of the ABCD rectangle

Correct result:

x =  5
y =  4

Solution:

u=AC S=AC/2 A0=2;A1=2 C0=8;C1=6  x=A0+C02=2+82=5
y=A1+C12=2+62=4
