The major axis of the eclipse is 12 units long
The given parameters can be represented as:
[tex]Red = 8[/tex]
[tex]Blue = 4[/tex]
See attachment for illustration
To solve this question, we make use of the following theorem
The distance between a point and the foci sums up to the major axis
This translates to:
[tex]Major\ axis = Red + Blue[/tex]
[tex]Major\ axis = 8 + 4[/tex]
[tex]Major\ axis = 12[/tex]
