Step-by-step explanation:
2(l · w)
2(24·15)
78
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:



Y=4
How?
When they say directly you should multiply the x and y together. You would get -24, now using that number divide -24 by the new x(-6) you would get 4.
A
x X x
= x^2
B
20 x 20 = 40
C
100 / 40 = 2.5 per square inch
