The parabola has a focus at (−3, 0) and directrix y = 3. what is the correct equation for the parabola? x2 = −12y x2 = 3y y2 = 3x y2 = −12x

Step-by-step explanation:

The distance between the parabola focus and the directrix is 3, then

Parabola vertex is placed on the perpendicular line to the directrix and this perpendicular line passes trough the focus. Its equation is x=-3 and parabola vertex coordinates are (-3,1.5).

Branches of the parabola go in negative y-direction, then the equation of the parabola is

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50
