It is 546.4583333333333, which would simplify to 546.46 if to the hundredths place or 546.5 to the tens place
Because its two 3s in the median i thought it give it a higher chance.
Answer:

Step-by-step explanation:
We are given the vertices of triangle ABC. We need to find the length of median AD.
Please see the attachment for figure.
D is mid point of BC because median bisect the opposite side of triangle.
Using the formula of mid point. we get coodrinate of D

D is mid point of B(1,5) and C(-3,-1)

AD is median of triangle ABC. Now we find length of median AD using distance formula of two coordinate.

A(5,1) and D(-1,2)


Thus, 
We need to divide 64/3 by the book thickness, 4/3. Since these two fractions have the same denominator, we can drop the 3's and focus on 64/4.
64/4 = 16
The third answer is the correct one. The other three answers aren't even close!
I’m not 100% but I think it could be the last table
