Area of an irregular polygon using side lengths in ios

Area of an irregular polygon using side lengths in ios

I am new to iOS, Currently i am working on to calculate the area of
polygon in the mapview. I have only lengths for the sides of an irregular
polygon, can anyone tell me how I can measure the area of the polygon?
Remember only lengths of all the sides , no angles or coordinates.
Few forums mention about trangulation of the polygon etc But I only have
side lengths.
Does anybody has any feedback?
Thanks.
