Step 1: Understand the question and examine the given figure

            NOTE:  ABC is an equilateral

                        A'B' parallel to AB

                        Side AB = 4 units


Step 2:  Check is there any relation between the triangles (ABC and CA'B').

           NOTE: Since A'B' is parallel to AB, triangles ABC and A'B'C are similar and

            therefore triangle A'B'C is also equilateral.


Step 3: Find the area of the triangle A'B'C

               NOTE: A = a^2 \frac{\sqrt{3}}{4}

                           A = 4^2 \frac{\sqrt{3}}{4}

                                       A = 4 \sqrt{3}
