An ellipse passes through the points 9 0 and 6 12 and is in

An ellipse passes through the points (9, 0) and (6, 12) and is in standard postion.

Assuming the equation of the ellipse is in the form
x^2/c^2 + y^2/d^2 = 1
then
c =
d =

substituting (9, 0) in the given equation we get

81/c^2 =1
=>c= 9

substituting (6, 12) in the given equation we get

36/c^2 + 144/d^2 =1
=>36/81 + 144/d^2 =1
=>144/d^2= 45/81

=>d^2 = 144*9/5
=>d = 36/5

this is the correct answer pls rate A+
