It's a rectangle.

A cylinder has 2 equal parallel flat surface circular bases and a curved surface body.
Yes, a cylinder has both curved and flat surface. Considering a solid cylinder standing on its end, the circular base and the circular top are flat surfaces. The surface connecting the top and bottom is curved.
A figure with 2 circular bases and one curved surface is called a cylinder. Examples are food cans.
An edge is a segment that is the intersection of two faces. A cylinder has two parallel bases bounded by congruent circles, and a curved lateral surface which connect the circles. Therefore, a cylinder does not have an edge.
