15.1 (The Triangle class) Design a class named Triangle that extends GeometricObject. The class contains the following: • Three double data fields named sidel, side2, and side 3 to denote three sides of the triangle. A no-arg constructor that creates a default triangle with each side 1.0. A constructor that creates a triangle with the specified sidel, side2, and side 3. • The constant accessor functions for all three data fields. ● A constant function named getArea() that returns the area of this triangle. A constant function named getPerimeter() that returns the perimeter of this triangle.

OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Question

In c++ Please help

15.1 (The Triangle class) Design a class named Triangle that extends
GeometricObject. The class contains the following:
• Three double data fields named sidel, side2, and side 3 to denote three sides
of the triangle.
• A no-arg constructor that creates a default triangle with each side 1.0.
A constructor that creates a triangle with the specified sidel, side2, and side3.
• The constant accessor functions for all three data fields.
●
• A constant function named getArea ( ) that returns the area of this triangle.
• A constant function named getPerimeter() that returns the perimeter of this
triangle.
Draw the UML diagram that involves the classes Triangle and GeometricObject.
Implement the class. Write a test program that prompts the user to enter three sides of the
triangle, enter a color, and enter 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 area, perimeter, color, and true
or false to indicate whether filled or not.
