I feel like Yandev with this terrible code, but what I did was trace along the path while marking every orthogonal unoccupied square on the grid with either an L or R depending on whether it's on my relative left or right while I travel along the loop. Then I make the Ls and Rs spread out along orthogonal squares using BFS until there's no more unoccupied squares. From there, I can tell where L or R is the enclosed area because the other one will be touching the edge of the grid, and I can just count them to get the answer.
