For each of the plane surfaces, calculate the exact surface area. (Answer in fractions)

(a)The surface composed of all surfaces bounded by the curve y = (sqr(x+6))+2, the x-axis, the y-axis and the line x = -15.

(b) The surface bounded by the curve y = 4sqr(x), the x-axis and the line y = 2x + 2 with the aid of vertical rectangles

(c) The surface bounded by the curve y - 4sqr(x), the x-axis and the line y = 2x + 2 with the aid of horizontal rectangles.
