The .area in shapely is plane area, so we need to transform longitude, latitude (4326) to project spatial reference (e.g. 3857).
For rectangle, if the original size is a * b, area is A, buffer distance is X, the buffer area B then:
B = A + 2 * (a + b) * X + pi * X * X ----- (1)
2 * (a + b) = c = perimeter = poly_B.length
(1) => X = sqrt(c * c - 4 * (...
Thanks for the comments! Turns out my shapefile was corrupted. I downloaded the data from the link that user2856 provided me and it works now. Really appreciate it. I spent way too long on it. Should have thought of that..
On Linux/Ubuntu, I needed to do something similar today and came up with the following solution.
