A "cross section" is what occurs when you "slice" a given shape in a particular way, so that you can visualise the shape in two parts (with 2 new faces). The cross section is the surface (face) of the side which you have just sliced.
E.g If you imagine a cone, with the circular base resting on a surface. You now slice the cone horizontally, so that you now have a very small cone (on top), and a "truncated cone" (2 circular faces, top one slightly smaller, with sloping sides joining them) below. The "cross section" is the top face of the truncated cone, and the lower face of the small cone (both cross sections are the same!). i.e they are the new "sides" that you have created. These new "faces" are both circular, so if you were to find the area you would use the formula pi*radius^squared = area.

Why Fluid Speed Increases in the Divergent Portion of a Convergent-Divergent nozzle?
Because the fluid is allowed to expand in the nozzle it increases velocity to fill in the voids created by the shape of the nozzle. The convergent point of the nozzle acts like a bottleneck trying to slow the fluid and compress it into the reduced crosssection of the nozzle. As it leaves the minimum crosssection it expands into the divergent spaces of the nozzle increasing in velocity as it expands. ++_+ No: it gains velocity through the convergence but in the diverging section, trades velocity for pressure.
