C Program to Find Area of Trapezium

This is a C Program to find area of trapezium.

This C Program calculates the area of trapezium.

The formula used in this program are Area = (1/2) * (a + b) * h where a and b are the 2 bases of trapezium & h is the height.

Here is source code of the C Program to Find the area of a right angled triangle.The C program is successfully compiled and run on a Linux system. The program output is also shown below.

 * C Program to Find Area of Trapezium
 */
#include <stdio.h>
 
int main()
{
    float a, b, h;
    float area;
 
    printf("Enter the value for two bases & height of the trapezium: \n");
    scanf("%f%f%f", &a, &b, &h);
    area = 0.5 * (a + b) * h ;
    printf("Area of the trapezium is: %.3f", area);
    return 0;
}

In this C program, library function defined in <math.h> header file is used to compute mathematical functions. We are reading the two bases and height of a trapezium using ‘a’, ‘b’ and ‘h’ variable. To find the surface area, the following formulas is used.

Area = (1/2) * (a + b) * h.

 
Output:
$ cc pgm25.c
$ a.out
Enter the value for two bases and height of the trapezium :
10 15 20
Area of the trapezium is: 250.000
