I have been trying to solve this one but i simply don't know how to. I asked my teacher about it and he said I should try to use the coefficient of similarity, but still no results. The task:

The bases of a truncated pyramid have the surfaces (areas) of 98cm^2 and 2cm^2. Whats the surface (area) of a section that cuts trough the truncated pyramid and goes trough the center of the truncated pyramid's height and is parallel with the bases.

Every help is welcome!

Thanks in advance.
