Explanation:
Let a = major axis
Let b = minor axis
Let c = focal length.
Consider the right focus, located a distance c from the center of the ellipse (at the origin).
From the right focus to the right point on the major axis is equal to a-c. This is the minimum distance.
From the right focus to the left point on the major axis is equal to a+c. This is the maximum distance.
Answer:
The correct option is A) 3 square inches;
.
Step-by-step explanation:
It is given that the length of the frame is (2x-3) and the width is (x-2)
The area of the rectangle is: 
Where, A is the area l is the length and w is the width of the rectangle.
Put
and
in the area of the rectangle.

The area of the frame expressed as a polynomial is
.
Now substitute x=3 in
.

The area of the frame is 3 square inches.
Hence, the correct option is A) 3 square inches;
.
