The ends are a half circle, joined by a long straight either side
100 meters is a quarter of a lap. 400meters is a quarter of a mile (or one complete lap)
The outer circle of a track is longer this is why the starting line is often set at an angle to the outside of the track.

That depends on the shape of the running track.
A standard running track is typically 400 meters long.
If you are looking for good track running shoes, be sure to check the tread based on what surface you are going to be running on. If your idea of track running is on a rubber track then you will want a tread that is shorter. For a shale track you will want something more like a cross trainer in order to get some traction with the running surface.
