Areas and perimeter What's interesting about fractals is their area and perimeter. If you have a polygon (X1. Y.).(*2.93),... (x. Yn), you can find the area via. (x:+1 - x:) y,+ Yit! . 0 11 and the perimeter via 3 (4141 x)2 + ... ,)? where we have used the convention that Xn+1 = xi and +1 = y. Write functions to implement the above and compute area and perimeter of a polygon det poly_area (polygon) ***Returns the area of a polygon... # YOUR CODE HERE 1 import math def poly perimeter (polygon) "Returns the perimeter of a polygon.*** # YOUR CODE HERE # Here you can test your code. YOUR CODE HERE Code Text Let us test both functions. 0 10 points: area and perimeter of polygons. polyi - ((0, 0), (1, 2), (2, 0)) assert poly_area (polyi) = 2 assert abs (poly_perimeter (polyi) 6.472)
