(144.31.12.99 <= -38.16.16.20) && /*Point #2*/

print("You are within this area");

As I explained in my previous post, that is not a rectangle so you can not do that. You have to check it against the equation of each line opposed to the points themselves. Cheking it your way also only works when the rectangle's sides are either perpendicular or parallel with the axis. |
