Question Analysis
This question focuses on applying the properties of the centroid of a triangle. The key is to use the ratio in which the centroid divides the median to find the lengths of and given the length of .
Key Concept Explanation
The centroid of a triangle divides each median in the ratio , where the segment from the vertex to the centroid is twice as long as the segment from the centroid to the mid - point of the side. In , since is the centroid and is a median, .
Step - by - Step Solution
1. Find the length of :
Given the ratio and . Let . Then, according to the ratio
