The answer is B) 7. PZ is half of PR, which makes RZ half of RP, making RZ also 7.

Answer: B) 7

Step-by-step explanation:

We know that a median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle.

  • Centroid : A point in a triangle where all the three medians of the triangle meet.

From the given figure, we can see that if C is the centroid of the triangle then QP must be a median of the triangle.

It implies the point Z must be the mid point of the line segment PR .

⇒ PZ=ZR

Therefore, RZ= 7 units .
