2. Design a class named Triangle that extends GeometricObject. The class contains: • Three double data fields named side1, side2, and side3 • A method named getArea() that returns the area of this triangle. • A method named toString() that returns a string description for the triangle. Hint: For the formula to compute the area of a triangle s (sidel + side2 + side3)/2; java area = Vs(s - sidel)(s - side2)(s - side3) The toString() method is implemented as follows: return "Triangle: side1 -" side14" side2-"4 side24 de3 -"
