Task: Design and Use Triangle Class – C++ Program

### Detail of C++ Program for Design and Use Triangle Class

Write a C++ Program to design a class Triangle with two float variables ‘base’ and ‘height’ and three member functions

1. void setBase(float b) to set value of base

2. void setHeight(float h) to set value of base

3. float area() to calculate area of triangle

with formula area = 1/2 x base x height.
