Write C Program to Find the Area of an Isosceles Triangle

//Write a C Program to Find Area of Isosceles  Triangle

#include <stdio.h>
#include <math.h>

int main()
{
    float a, b, area;

    printf("Enter Length of Isosceles Triangle's Same Sides :--> ");
    scanf("%f", &a);

    printf("Enter Length of Isosceles Triangle's Third side :--> ");
    scanf("%f", &b);

    //formula to find the area of the Isosceles triangle
    area = (b * sqrt((4 * a * a) - (b * b)))/4;

    printf("The Area of the Isosceles Triangle :--> %.2f\n", area);

    return 0;
}

Output:

Enter Length of Isosceles Triangle's Same Sides :--> 6
Enter Length of Isosceles Triangle's Third side :--> 8

The Area of the Isosceles Triangle :--> 17.89
