I want to convert a set of 5 Lat Long (Directly taken from Google Map) into Sq Meter area.
As 5 points are there I have found the formula on : (Converting Longitude and Latitude Coordinates to Square Miles?)

area = rad(x2 - x1) * (2 + sin(rad(y1)) + sin(rad(y2))) + rad(x3 - x2) * (2 + sin(rad(y2)) + sin(rad(y3))) + rad(x4 - x3) * (2 + sin(rad(y3)) + sin(rad(y4))) + rad(x5 - x4) * (2 + sin(rad(y4)) + sin(rad(y5)))

area = abs(area * 6378137.0 * 6378137.0 / 2.0)

but this formulae dint giving me the correct area,
I am putting the latitude in x & Longitude in y
also as digit after decimal places change the answer changes (obviously)
(ex 20.011619, 73.762870 have 6 digits after decimal)

so what is the correct method to use this formula with lat, long? & do I want to convert lat-long into another measure to get the area correctly?
