Question 1103741
.
There is well known property of medians of a triangle:


<pre>
    In any triangle, medians are concurrent and their common intersection point 

    divides each median in proportion 2:1, counting the median parts from the vertex.



So, if DG = 32 cm,  then  AG = 64 cm, and the entire median AD is 32 + 64 = 96 cm.
</pre>

Solved.


On the property of medians, see the leson
