Property: The medians of a triangle divide the triangle into 6 parts with equal areas.
Step 1: Draw the remaining median from vertex B to the midpoint of its opposite side/segment AC.
The three medians of ΔABC with centroid at F now divide the triangle into 6 equal parts.
Step 2: Given that the area of one of the 6 triangle formed by the medians, Δ EFA, is 1 cm², solve for the area of Δ ABC:
Area of Δ ABC = 6 (1 cm²)
Area of Δ ABC = 6 cm²
ANSWER: The area of Δ ABC is 6 cm².
