How would you use the Green's Theorem to evaluate the line integral below...?

Using the Green's Theorem to evaluate the line integral

∫ P(x, y) dx+ Q(x, y) dy

C

where C is the path from (0, 0) to (1, 0) along y = 0; then from (1, 0) to (1, 1) along x = 1; then from (1, 1) to (0, 0) along y = x^1/2, given that P(x, y) = y^8, and Q(x, y) = 6xy.

This are the possible answers in the back of the book....

a. 1

b. 11/10

c. 7/6

d. 17/14

e. 5/4

f. 23/18

g. 13/10

h. 29/22

i. 4/3

or is it none of these?
