Below we will dene an n-interesting polygon. A 1-interesting polygon is just a square with a side of length 1. An n-interesting polygon is obtained by taking the n 1-interesting polygon and appending 1-interesting polygons to its rim, side by side. You can see the 1, 2, 3 and 4 - interesting polygons in the picture below. Write an algorithm to nd the area of a polygon for a given n. (5 points) 1. For n = 1, the output should be ShapeArea(1) = 1 2. For n = 2, the output should be ShapeArea(2) = 5 3. For n = 3, the output should be ShapeArea(3) = 13 Hint: Your method should take n as a parameter.
