Answer:

Option D.
KR=17.2\ mm

Explanation:

we know that

The Centroid of a Triangle is the center of the triangle that can be calculated as the point of intersection of all the three medians of a triangle. The centroid divides each median in a ratio of
2:1

In this problem the point R represent the centroid of triangle JKL

therefore


KR=(2/3)KM

substitute the value


KR=(2/3)(25.8)=17.2\ mm
