Whichever segment it is to which you are referring, it does not need to be red; it can be any color.The segment that intersects both foci is called the semi-major axis. The segment that is perpendicular to the semi-major axis with one end midway between the foci is called the semi-minor axis.
The length of the major axis of an ellipse is determined by the lengths of its semi-major and semi-minor axes. In this case, if the red line segment represents the semi-major axis (8), the length of the major axis would be twice that, which is 16. The blue line segment, being shorter (4), represents the semi-minor axis. Thus, the major axis of the ellipse is 16 units long.

The answer will depend on what, if anything, the line segments have to do with the ellipse.
The Answer Is 9.5
The length of the major axis of an ellipse is equal to twice the length of the semi-major axis. If the semi-major axis is denoted as "a," then the major axis length is 2a. This axis is the longest diameter of the ellipse, stretching from one end of the ellipse to the other through the center.
