How would i find area using 4 gps coordinate

i need to find how many acres are inside 4 gps coordinates (37.59251 N, 112.50740 W), (37.59333 N, 112.50807 W), (37.59498 N, 112.50473 W), and (37.59111 N, 112.50305)

Assuming this is a flat polygon (since the coordinates are rather close together)...


37.59111 112.50305
37.59498 112.50473
37.59333 112.50807
37.59251 112.50740

-0.372233739
0.311200038
0.067069086
-0.006017059

9.1634E-06 304704
2.792124675

I got around 2.8 acres.

You use the shoe lace formula.
