- What a nice parallelogram!
- I am glad you like it.
- What is that question mark doing in the center?
- I have tried to calculate the area of BQP, but so far without any luck.
- 6, 17, and 29 are the area of the triangles they are in?
- You are right. The problem is to find the area of the fourth triangle.
- Have you tried subtraction?
