Answer:

  • 8 units

Step-by-step explanation:

First, let's review the definition of horizontal.

  • Definition of horizontal: A line such that perpendicular to the vertical line.

In the picture given, we can see that DE is the vertical line and CD is the horizontal line. I have uploaded a picture. To find the length of CD (horizontal line), simply count the red dots. After counting, there was a total of 8 dots.

Hence, the length of CD is 8 units.
