`M` is the foot of the perpendicular from a point `P` on a parabola `y^2=4a x` to its directrix and `S P M` is an equilateral triangle, where S is the focus. Then find `S P` .

M is the foot of the perpendicular from a point P on a parabola y^(2)=4ax to its directrix and SPM is an equilateral triangle,where S is the focus.Then find SP.

If M is the foot of the perpendicular from a point P on a parabola to its directix and SPM is an equilateral triangle where S is the focus then SP=
