C Language program to calculate triangle area


Following program shows you how to calculate triangle area.
This program gets triangle base and height from user and calculates area and prints it using following formula
Area = base X height / 2

#include <stdio.h>

int main() {
	float triangleBase;
	float triangleHeight;

	printf("Enter the base of triangle:");
	scanf("%f", &triangleBase);

	printf("Enter the height of triangle:");
	scanf("%f", &triangleHeight);

	float areaOfTriangle = (triangleBase * triangleHeight) / 2;
	printf("Area of triangle is: %f", areaOfTriangle);
}

Output:

Enter the base of triangle: 45
Enter the height of triangle: 20
Area of triangle is: 450.000000
