计算梯形面积和周长的程序

梯形是至少有一对平行边的四边形，其他两条边可能不平行。平行的边称为梯形的底边，另外两条边称为梯形的边。平行边之间的垂直距离称为梯形的高度。

公式 ：

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

例子 ：

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

下面是上述公式的实现：

C++

// CPP program to find area
// and perimeter of trapezium
#include 
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;
}

Java

// Java program to calculate area
// and perimeter  of Trapezium

                                float b, float h)
    {
        return ((a + b) * h) / 2;
    }
     
    // Function to perimeter of Trapezium
    public static float perimeterTrapezium (float a,
                            float b, float c, float d)
    {
        return (a + b + c + d);
    }
 
     
 
// Driver function
public static void main(String args[])
{
 
    // 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));
}
