Answer:
Step-by-step explanation:
Consider triangle ABC with the base AC=36. Let the line DE be parallel to the line AC. If DE||AC, then triangles ABC and DBE are similar. If k is the scale factor of these triangles, then
Thus,
The area of the triangle ABC is
The area of the triangle DBE is
Since line DE divides triangle ABC in two equal area parts, we have that
and
