In a diagram, two surfaces are partially
superimposed in each other. The perimeter of one
surface is 201 units and the area is 201 square units.
The perimeter of the other surface is 710 units and
the area is 710 square units.
What is the difference of the area of the two surfaces
that is not black shaded, i.e., common between two?
