Given :
Three points , P(4, 3, 4), Q(2, 1, 3), R(2, 7, 0) .
To Find :
The length of sides .
Given :
We know , length of two points P(x,y ,z) and Q(a,b,c) is given by :

Length of PQ :

Length of QR :
:
Length of RP :

Hence , this is the required solution .
B
Because 2 sqrt5 is = to sqrt 20.
4^2=16, 6^2=36
14.80+5%=15.54 and to get to that answer we have to add 8.41 and 7.13 and you will get 15.54.
Answer:
12
Step-by-step explanation:
Count the units in between the points
