Problem number 8

Write a program segment that will ask the user if he wants to compute the perimeter or the area of a triangle. If the perimeter is wanted, ask the measure of the three sides and compute for the perimeter. If the are is wanted, ask for the measures of the base and height and compute for the area. Display the computed value.
