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.
To determine the length of the red segment, we need additional context about the geometric figures involved. Typically, if the blue line segment represents a distance related to the transverse axis of an ellipse or hyperbola, one might apply the relationship between the axes and the segments to find the red segment's length. However, without knowing how the blue segment and the red segment are related to the transverse axis, it's impossible to provide a specific answer. Please provide more details about the geometric configuration.
