# Thread: Line integral and Green's theorem

1. ## Line integral and Green's theorem

Hey guys, I tried to solve this problem "million" times and I can't get the same result. Can you see what is wrong here, please?

if $L_3$ is from $B$ to $A$ (positive orientation) then we get

$$\int _{L_1}= 2$$

$$\int _{L_2}= \frac{2}{3}$$

$$\int _{L_3}= 2$$

and by Green's Theorem we get twice the area enclosed which gives $\frac{14}{3}$
