Problem
Use pseudocode to design a suitable program to solve it. In your program, make use of subprograms or functions with parameters and arguments. Note: some of the Programming Challenges will require some reworking to be implemented in RAPTOR.
Develop a menu-driven program that inputs a number X, and at the user's choice, finds and displays the area (A) of one of the following:
? A square with side X (use A = X^2)
? A circle with radius X (use A = 3.14 * X^2)
? An equilateral triangle with side X (use A = (3)/4 * X^2) Use a function for the area of each shape.
