(The Triangle class) Design a class named Triangle that extends the GeometricObject class. The Triangle class contains - Three float data fields named side1, side2, and side to denote the three sides of the triangle. - A constructor that creates a triangle with the specified side1, side2, and side with default values 1.0. - The accessor methods for all three data fields. - A method named getArea() that returns the area of this triangle. - A method named getPerimeter() that returns the perimeter of this triangle. - A method named_str_ that returns a string description for the triangle. For the formula to compute the area of a triangle, see Exercise 2.14. The_str__() method is implemented as follows: return "Triangle: side1 = " + str(side1) + " side2 = " + str(side2) + " side3 = " + str(side3) Draw the UML diagrams for the classes Triangle and Geometricobject Implement the Triangle class. Write a test program that prompts the user to enter the three sides of the triangle, a color, and 1 or 0 to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the color and filled properties using the input. The program should display the triangle's area, perimeter, color, and True or False to indicate whether the triangle is filled or not. Sample Run Enter side1: 2.5 Enter side2: 3.1 Enter side3: 2.8 Enter color: red Enter 1/0 for filled (1: true, : false): 1 The area is 3.3159613990515604 The perimeter is 8.399999999999999 Color is red Filled is True
