5.2.4: Area of Triangle Write a function that computes the area of a triangle given its base and height.

The formula for an area of a triangle is:

AREA = 1/2 * BASE * HEIGHT

For example, if the base was 5 and the height was 4, the area would be 10.

triangle_area(5, 4); # should print 10

Your function must be named triangle_area

Note: Be sure to include comments for all functions that you use or create.
