Write a program that declares a shape class as abstract class. There are two classes (all sides are equal) and Right Triangle being derived from shape class. Write suitable program to calculate the area and perimeter of relevant shapes ( i.e Right Triangle and square). Formulas used to calculate the area and perimeter are as follows:
- Area of square = (side)2
- Perimeter of square = 4*side
- Are of Right Triangle = ½ * base * height
- Perimeter of Right Triangle = side1 + side2 + side3
