In order to find the length of the side CD in the pentagon ABCDE we would need to find the distance between the two points (4,-2) and (8, 2)

We would use the following formula:

$d=\sqrt[]{(x1-x2)^2+(y1-y2)^2}$

plug in x1= 4, x2= 8, y1=-2, y2=2

So,

$d=\sqrt[]{(4-8)^2+(-2-2)^2}$
$d=\sqrt[]{(-4)^2+(-4)^2}$
$d=\sqrt[]{32}$

d=5,65

The length of the side CD in the pentagon ABCDE would be 5,62
