Answer:
→→Parabola is the locus of all the points in the plane such that distance from a fixed point called focus to distance from a fixed line called directrix are equal.
→It is given that a green point lies on the parabola.
Distance of green point from Focus = 7 unit
By the definition of parabola
→Distance of green point from Directrix = Distance of green point from Focus
→Distance of green point from Directrix = 7 unit
