Write a program that simulates a simple menu system. The menu should have the

following options:

$-$ Calculate the area of a square.

$-$ Calculate the area of a circle.

$-$ Calculate the area of a triangle.

$-$ Quit the program.

Use functions to perform the calculations for each option, and it should continuously

display the menu and prompt the user for their choice until they choose to quit.

Sample Input and Output:

$1.$ Area of a square

$2.$ Area of circle

$3.$ Area of triangle

$4.$ Quit

Choose your operation: $3$

Enter the base of the triangle: $3$

Enter the height of the triangle: $6$

Area: $9\mathrm{.}00$

$1.$ Area of a square

$2.$ Area of circle

$3.$ Area of triangle

$4.$ Quit

Choose your operation: $4$

GoodBye!
