Find the GPS locations for Atlanta, Georgia; Orlando, Florida; Savannah, Georgia; and Charlotte, North Carolina from www.gps-data-team.com/map/ and compute the estimated area enclosed by these four cities.

use formula d= radius x arccos ( sin(x1) x sin(x2) + cos(x1) x cos(x2) x cos(y1 - y2))

Atlanta, GA :-84.4580600 , 33.6277100

Orlando, FL:-81.3065200 , 28.4562700

Savannah, GA:-81.0845000 , 32.0794000

Charlotte, NC:-80.8309220 , 35.1087160

a = float(input('Enter first side: '))

b = float(input('Enter second side: '))

c = float(input('Enter third side: '))

# calculate the semi-perimeter

s = (a + b + c) / 2

# calculate the area

area = (s*(s-a)*(s-b)*(s-c)) ** 0.5

print('The area of the triangle is %0.2f' %area)
