Answer
$CP = 13.2$
Work Step by Step
In a parallelogram, diagonals bisect one another. If diagonal $\overline{CP}$ is bisected by diagonal $\overline{AE}$, then the bisected segments $\overline{CR}$ and $\overline{RP}$ are equal to one another.
In this exercise, we want to find $CP$, so we would need to add $CR$ and $RP$ together. If $CR$ and $RP$ both equal $6.6$, then we would add them together to find $CP$:
$CP = CR + RP$
Let's plug in what we know:
$CP = 6.6 + 6.6$
Add to solve:
$CP = 13.2$
