Logic to find area of triangle 

Steps for finding area of a triangle were discussed below: 
 Input base of the triangle say “b” and store in some variable say “base”.
 Input height of the triangle say “h” and store in some variable say “height”.
Use the formula for calculating area of the triangle, area = (base * height) / 2
 Print the resultant area of the triangle.

 

Program to find area of triangle

#include <stdio.h>
 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);
}


 Example

INPUT
Enter the base of the triangle: 5
Enter height of the triangle: 6
OUTPUT
 Area of the triangle = 15 sq. units
