how to calculate length of triangle

Question: Write a program that defines the abstract base class shape and derives five Derived classes: cricle (circle, square (square, rectangle (rectangle), trapezoid (trapezoid ), triangle (triangle ). use virtual functions to calculate the area

Starting from this chapter, we will learn about triangle learning and apply it to animation technology in chapter 5.It will be exposed during the graphic technique. If you already know about triangle learning or want to learn about animation, you
