A trapezium is a quadrilateral with at least one pair of parallel sides, other two sides may not be parallel. The parallel sides are called the bases of the trapezium and the other two sides are called it’s legs. The perpendicular distance between parallel sides is called height of trapezium.
 

Formula : 
 

Area of Trapezium : 0.5 * (a + b) * h
Perimeter of Trapezium : a + b + c + d

Examples : 
 

Input :  a = 5, b = 6, c = 4, d = 3, h = 8
Output : Area of Trapezium : 44
         Perimeter of Trapezium : 18

Input :  a = 10, b = 15, c = 14, d = 11, h = 21
Output : Area of Trapezium: 262.5
         Perimeter of Trapezium: 50

 

Below is the implementation of above formula : 
 

C++




// CPP program to find area
// and perimeter of trapezium
#include <bits/stdc++.h>
using namespace std;
  
// Function to calculate Area of trapezium
float areaTrapezium(float a, float b, float h)
{
    return (1.0 / 2 * (a + b) * h);
}
  
// Function to calculate perimeter of trapezium
float perimeterTrapezium(float a, float b, float c, 
                                           float d)
{
    return (a + b + c + d);
}
  
// Driver function
int main()
{
    float a = 5, b = 15, c = 11, d = 4, h = 20;
    cout << "Area of Trapezium = " << 
                areaTrapezium(a, b, h) << endl;
    cout << "Perimeter of Trapezium = " << 
                perimeterTrapezium(a, b, c, d);
    return 0;
}

    {
        return ((a + b) * h) / 2;
    }
      
    // Function to perimeter of Trapezium
    public static float perimeterTrapezium (float a,
                            float b, float c, float d)
    {

    }
  
      
  
// Driver function

{
  
    // a, b, c, d are four sides of Trapezium 
    // and h is height between two parallel sides.
    float a = 5;
    float b = 15;
    float c = 11;
    float d = 4;
    float h = 20;
  
    // Printing value of  area.
    System.out.print("Area Of Trapezium : ");
    System.out.println(areaTrapezium (a, b, h));
      
    // Printing value of  Perimeter. 
    System.out.print("Perimeter Of Trapezium : ");
    System.out.println(perimeterTrapezium (a, b, c, d));
