Use the information provided to write the standard form equation of each ellipse. 1) Vertices: (11, 5), (-15, 5)
Foci: (10, 5), (-14, 5)

2) Vertices: (-4, 17), (-4, -9)
Foci: (-4, 9), (-4, -1)

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
