In triangle $ABC$,point $D$ is the midpoint of $BC$and point $E$ is the midpoint of $AC$.If $AD=6$,$BE=9$,and $AC=10$ then find the area of triangle $ABC$.
I've solved this problem in two ways:
$1)$ by constructing the third median and calculating the area of one of the triangle determined by the intersection of the medians then multipy by six.
$2)$ by calculating the lengths of the other two unknown sides and then applying Heron's Formula.
Now what i am asking is if someone can come up with another solution based on geometric methods.
P.S:you may ask the why of this question and the answer would be that i like to see many creative solutions to one problem,and see what is the most beautiful one.
Thanks in advance
