I have a study region with an area of 1 that has several lakes, one with an island. The total lake area happens to be 0.27. In total 20 random points were placed into this study region. Furthermore, randomly 10 point pairs were connected by straight lines. How can we estimate the area of the lake using 20 sample points. I know that we get the coordinates of the points. But how can we use them in estimating the area of the lake. How can we use estimate the area of the lake using 10 random lines as given in the figure.Similarly here we can find the length of the lines using coordinates, but how this helps in estimating area.
