The distance from point C to point D is a units option (C) is correct.
What is a distance formula?
It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We have:
Parallelogram ABCD in the coordinate plane so that A is (0,0), B is (a,0), C is (a, b), and D is (0, b).
The distance between C to D
[tex]\rm d=\sqrt{(0-a)^2+(b-b)^2}[/tex]
[tex]\rm d=\sqrt{(a)^2}[/tex]
d  = a units
Thus, the distance from point C to point D is a units option (C) is correct.
