Write a Python program to compute and print the perimeter, the semiperimeter, and the area of a triangle, given the lengths of the 3 sides of the triangle. Make sure to change "your name" to your actual name in line 3 of lab1.py and add your section to line 5 . Problem Description: An example triangle has sides of length (call them side1, side2, and side3) 3,4, and 5 Now you can calculate the permiter, the semiperimeter, and the float area of a triangle, using the following formulas: Now you can calculate the permiter, the semiperimeter, and the float area of a triangle, using the following formulas: Perimeter = side + side 2+ side 3 Semiperimeter = Perimeter /2 Area = SquareRootOf(Semiperimeter (Semiperimeter - side1)(Semiperimeter (Semiperimeter - side3)) The program should adhere to the following pseudocode: 1. Prompt for and read the first side 2. Prompt for and read the second side 3. Prompt for and read the third side 4. Calculate the perimeter (see formula above) 5. Calculate the semiperimeter (see formula above) 6. Calculate the area (see formula above) 7. Display the results.
