Extracted text: 100% Exercise 1: Write a python program that reads from a text file whose name is provided by the user and including lines relating to the dimensions of three kinds of shapes: Circle, Triangle, Trapezoid (see figure below for a sample input file). For each shape compute and display its area: - Triangle area = base X height. 2 A Circle area = n radius?. - Trapezoid area = (base , + base,)X height. 2 Your program should consider the following erroneous cases: • The file does not open/exist The format of the data in the file is incorrect (e.g. shape name = 'Polygon'), the shape's I dimensions are incorrect (e.g. negative value or number of values for a trapezoid not equal to 3: base,, base, and height, or), in which case RuntimeError exception should be raised and the processing should continue. 48 Shape Area Triangle: Circle: -10 50 1200.00 >> invalid dimension 770.00 Triangle Trapezoid: 10 12 70 Trapezoid: 32 Circle Trapezoid Trapezoid >> missing data.
