## Algorithm

1. Input base of the triangle. Store in some variable say base.
2. Input height of the triangle. Store in some variable say height.
3. Use triangle area formula to calculate area i.e. `area = (base * height) / 2`.
4. Print the resultant value of area.

Area of a triangle

Area of a triangle is given by formula.

Where b is base and h is height of the triangle.

## Code Examples

### #1 Example-C programing to find the area of a triangle

```Code - C Programming```

``````#include <stdio.h>
#include <math.h> /* It is ecessary for using sqrt function  */

void main()
{
/*Variable Declaration*/
float a, b, c, s, area;

/*Taking user input*/
printf("Enter the three sides, a, b, and c, of the triangle:");
scanf("%f%f%f", &a, &b, &c);

/*Calculate the area of the triangle*/
s = (a + b + c) / 2;
area = sqrt((s *(s - a) *(s - b) *(s - c)));
printf("\n The area of the triangle is %f.", area);
}``````
Copy The Code &

Output

cmd
Enter the three sides, a, b, and c, of the triangle:
15
10
15
The area of the triangle is 70.710678.

### #2 Example-Programing to find area of a triangle

```Code - C Programming```

``````/**
* C program to find area of a triangle if base and height are given
*/

#include <stdio.h>

int main()
{
float base, height, area;

/* Input base and height of triangle */
printf("Enter base of the triangle: ");
scanf("%f", &base);
printf("Enter height of the triangle: ");
scanf("%f", &height);

/* Calculate area of triangle */
area = (base * height) / 2;

/* Print the resultant area */
printf("Area of the triangle = %.2f sq. units", area);

return 0;
}``````
Copy The Code &

Input

cmd
Enter base of the triangle: 10
Enter height of the triangle: 15

Output

cmd
Area of the triangle = 75 sq. units
