Extracted text: 9 /11 100% 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 = 2 base X height. → Circle area n radius2. - Trapezoid area = ; (base 1 + base2)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 dimensions are incorrect (e.g. negative value or number of values for a trapezoid not equal to 3: base,, basez and height, or), in which case RuntimeError exception should be raised and the processing should continue. 50 48 Shape Area Triangle: Circle: -10 Triangle Circle 1200.00 Trapezoid: 10 12 70 Trapezoid: >> invalid dimension 770.00 >> missing data. 9 32 Trapezoid Trapezoid Sample input file Sample output
