C Program to find the Area of Triangle using Base and Height

Below is a program to find the area of triangle using base and height.

#include<stdio.h> int main() { printf("\n\n\t\tStudytonight - Best place to learn\n\n\n"); int h, b; float area; printf("\n\nEnter the height of the Triangle: "); scanf("%d", &h); printf("\n\nEnter the base of the Triangle: "); scanf("%d", &b); /* Formula for the area of the triangle = (height x base)/2 Also, typecasting denominator from int to float to get the output in float */ area = (h*b)/(float)2; printf("\n\n\nThe area of the triangle is: %f", area); printf("\n\n\t\t\tCoding is Fun !\n\n\n"); return 0; }

Output:

Program to find the Area of Triangle using Heron's Formula

Below is a program to find the area of triangle using heron's formula.

#include<stdio.h> #include<math.h> // to use sqrt() function int main() { printf("\n\n\t\tStudytonight - Best place to learn\n\n\n"); double a, b, c, area, s; printf("\nEnter the sides of the triangle:\n\n"); scanf("%lf%lf%lf", &a, &b, &c); // lf is format specifier for double input s = (a+b+c)/2; /* sqrt is a predefined system function that returns the square root of the input value */ area = sqrt(s*(s-a)*(s-b)*(s-c)); printf("\n\n\n\nThe area of the Triangle calculated using Heron's formula is: %lf", area); printf("\n\n\t\t\tCoding is Fun !\n\n\n"); return 0; }
