In δpqr, point c is the centroid. if pz = 7, then rz =
a) 3.5
b) 7
c) 14
d) 21

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.

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 .

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

168

step-by-step explanation:

i am pretty sure that the answer is 168
