# Program to calculate the area of a Tetrahedron

A tetrahedron is a pyramid with triangular base i.e. it has a base that is a triangle and each side has a triangle. All the three triangles converge to a point. As in the figure,

Area of Tetrahedron = (√3)a2

## Example

The code to find the area of tetrahedron uses the math library to find the square and square-root of a number using sqrt and pow methods. For calculating the area we take a floating point and the value of the expression "((sqrt(3)*a*a))" is given to it.

#include <stdio.h>
#include <math.h>
int main() {
int a= 5;
float area, volume;
printf("Program to find area and volume of Tetrahedron
");    printf("The side of Tetrahedron is %d
", a);    area = (sqrt(3)*(a * a));    printf("The area of Tetrahedron is %f
", area);    return 0; }

## Output

Program to find area and volume of Tetrahedron
The side of Tetrahedron is 5
The area of Tetrahedron is 43.301270
