Variables Exercises: Part B

We would like a program that can figure out the area of a triangle
with a specific base and height.
Write this program for us!
Use appropriate variable names and types.
Use various values to test your program and check your output 
against a calculator.

Tips:

The formula for area of a triangle is .5 *base * height   
(did you ever wonder why this is?  Think about it, if we did 
base * height, that would give us the area of a rectangle.  But a triangle
 is just a half a rectangle.  If you smush two of the same triangles 
 together, they make a rectangle so it makes sense that the area of one 
 of the rectangles would be half of the area of the rectangle - neat eh?)

Don't forget to output your answer in a professional and 
user-friendly way!
