Read Solution (Total 2)
-
- You know that the centroid is two thirds of the distance from each vertex to the
midpoint of the opposite side.
8=AP=2/3AD => AD=12
6=BP=2/3BF => BF=9
12=CA=2/3CE => CE=18
by using these values we find
AB=4(root7) AC=2(root55) BC=12(root3)
perimeter=4(root7)+2(root55)+12(root3) - 11 years agoHelpfull: Yes(1) No(0)
