Given data:
The coordinnate of H is (1,1).
The coordinate of J is (2,3).
The coordinate of K is (6,3).
The coordinnate of L is (5,1).
The above coordinate represents the parallelogram and diagonal of the parallelogram intersects at the mid point.
The x-cordinate of the diagonal is,
x=(1+6)/2
=7/2
The y-coordinnate of the diagonal is,
y=(1+3)/2
=2
Thus, the coordinate of the intersection of the diagonal is (7/2, 2).
