The assignment has three questions. Question #1: [30 marks] A regular polygon is an n-sided polygon in which all sides are of the same length and all angles have the same degree (i.e., the polygon is both equilateral and equiangular). The formula for computing the area of a regular polygon is Here, s is the length of a side. Write a program that prompts the user to enter the number of sides and the length of a regular polygon and displays its area rounded to three decimal places. Here is a sample run: Figure 1: Sample Run Hint: start your program with the following statement, which allows you to use the tan function and pi constant. from math import tan, pi Example: print(tan(pi)) #answer is -1.2246467991473532e-16 Source Code: [Instruction: copy and paste the source code here] from math import tan, pi num=int(input("Enter number of sides: ")) sides=float(input("Enter the side length: ")) Area=num*(sides**2)/(4*tan(pi/num)) print ("The area of the polygon is", format(Area,".3f")) Alfaisal University - College of Engineering Software Engineering Department SE 100: Programming for Engineers Assignment #4 Fall 2022 - Due Date: Oct 06, 2022 at 11:59pm (midnight) Question #3: [35 marks] At a particular university, letter grades are mapped to grade points in the manner given in Figure 4. Write a program that begins by reading a letter grade from the user. Then, your program should compute and display the equivalent number of grade points. Ensure that your program generates an appropriate error message if the user enters an invalid letter grade. Figure 5: Grading System Note: You can use .upper() to convert any lowercase letters entered by the user to uppercase letters, storing the result back into the same variable.
