C Program to find Area of a Trapezoid

In this article we will show you, How to write C Program to find Area of a Trapezoid and Median of a Trapezoid with example. Before we step into practical example, Let see the definitions and formulas behind the Median and Area of a Trapezoid

Area of a Trapezoid

If we know the height and two base lengths then we can calculate the Area of a Trapezoid using the below formula:

Area = (a+b)/2 *h

Where a and b are the two bases and h is the height of the Trapezoid

We can calculate the median of a Trapezoid using the following formula:

Median = (a+b) / 2.

If we know the Median and height then we can calculate the Area of a Trapezoid as: median*height

C Program to find Area of a Trapezoid

This C Program allows the user to enter both sides of the Trapezoid and height. Using those values we will calculate the Area of a trapezoid and Median of a Trapezoid.

/* C Program to find Area of a Trapezoid */

#include<stdio.h>

int main()
{
  float base1, base2, height, Area, Median;
 
  printf("\n Please Enter two bases and height of the trapezium \n");
  scanf("%f %f %f", &base1, &base2, &height);

  Area = 0.5 * (base1 + base2) * height;
  Median = 0.5 * (base1+ base2);

  printf("\n Area of a trapezium = %.2f \n", Area);
  printf("\n Median of a trapezium = %.2f \n", Median);

  return 0;
}

OUTPUT

ANALYSIS
Below printf statement will ask the user to enter base1, base and height values

 printf("\n Please Enter two bases and height of the trapezium \n");

Below scanf statement will assign the user input values to respected variables. Such as first value will be assigned to base1, second value to base2 and third value to height

 scanf("%f %f %f", &base1, &base2, &height);

User Entered Values are base1 = 6, base2 = 9 and height = 4

Area of a Trapezoid = 0.5 * (base1 + base2) * height;
Area of a Trapezoid = 0.5 * (6 + 9) * 4;
Area of a Trapezoid = 0.5 * 15 * 4;
Area of a Trapezoid = 30

Median of a Trapezoid = 0.5 * (base1+ base2);
Median of a Trapezoid = 0.5 * (6 + 9)
Median of a Trapezoid = 0.5 * 15
Median of a Trapezoid = 7.5
