A median in a triangle is a line segment drawn from an angle to the midpoint of the opposite side. The medians of a triangle all intersect in one point. This point divides each median in the ratio .
let be a triangle
if CM[1]=15...it is equal to the hight of triangle , , and
if intersection point of all three medians is , and is median then
.......=> and

and .......=> and
now we can find which is half of base





...........so, the base

then the area will be:
