A Parabolic archway is 12 meters high at the vertex, at a height of 10 meters, the width of the archway is 8 meters. How wide is the archway at ground level?

2. Relevant equations

given in the picture it has (-4,10) and (4,10) along with vertex (0 ,12)

3. The attempt at a solution

(y- 12)^2 =4p(x - 0)

12 = 4p(0) p = 3 ?? I dont know if i need this

i have a picture but not sure what i need to do
