 abstract={An iterative procedure for estimation of the area surrounded by a simple closed curve in the real 2D space is proposed. We employ the Pick’s Formula for calculating the area surrounded by a special types of polygons. Starting from an initial grid-step and ending up with a smaller grid-step - satisfactory to be able to build the inner and outer polygons. We propose in this paper also a formula for intuitionistic fuzzy estimation for the area surrounded the curve. The proposal is a numerical method allowing to program the algorithm in any procedural language. The iterative process stops when a satisfactory small enough limit between the upper and lower estimation has been reached.},
