## Homework Statement

On the picture, compare the area of triangle ABC to the area of A'B'C'.

This problem was shown to me by a 13 years old. Trigonometry forbidden. It seems to me that this is the kind of problem you either solve in 2 minutes, or never solve. In both cases, you don't learn anything. Is this designed to frustrate students or is there any content in this? Your opinion please.
