# Area of a triangle inside a parallelogram in C++

The area of a figure is the extent of the figure in two-dimensional plane.

**Triangle** is a polygon with three sides.

**Parallelogram** is a quadrilateral with opposite sides equal and parallel.

In this program, we have a parallelogram with its base and height and it inscribed a triangle the same base as the parallelogram. We need to calculate the area of the triangle using the given base and height.

Area of triangle constructed take the base of a parallelogram and common height as the parallelogram is given by the formula = **0.5 * base * height**

area = ½ * b * h

## Example

#include<iostream> #include<math.h> using namespace std; int main(){ float b, h, Area; b = 30.0; h = 22.0; Area = (0.5 * b * h); cout<<"Area of triangle with base "<<b<<" and height "<<h<<" is "<<Area; return 0; }

## Output

Area of triangle with base 30 and height 22 is 330
