This is another textbook number that doesn't have the solution and I can't figure it out. Any tips would be greatly appreciated.

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.
