This is our De(S)sert Island

Our Paradise has got a contour: the line of the sea shore. We need to know how many kilometres of

beaches we’ve got.

To find out the perimeter, we divide the contour line into short segments. Now we measure each segment

by mean of the straightedge and sum all the segments. Those are linear kilometres.

Our island also has got a surface: the two-dimensional space we can walk about and…build skyscrapers.

To measure the area of the island, we make triangles all over, and calculate the

area of each triangle. Then sum all the areas. Those are square kilometres.
