Can somebody please tell me what to do here?
Important: A median divides a triangle into two triangles of equal area.
If the area of a ΔDEF is 17, then the area of ΔADE = 17 * 4 = 68
Area of ΔADE = 68 ...then.... area of ΔADC = 68 * 3 = 204
Area of ΔABC = 204 * 2 = 408 u2
This diagram may support my answer. If an explanation is needed, I'm willing to provide it.
