Answer:
225
Step-by-step explanation:
3240k = 2×2×2×3×3×3×3×5×k
Every factor should be in groups of 3
(3×5)² = k
k = 225
The major axis of the eclipse is 12 units long
The given parameters can be represented as:


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:
