查找梯形区域的程序

梯形的定义：
梯形是具有至少一对平行边的凸四边形。平行的边称为梯形的底，不平行的另外两个边称为支腿。也可以有两对碱基。

上图中的CD || AB，因此它们形成了底脚，另两个侧面(即AD和BC)形成了支脚。
梯形的面积可以通过以下简单公式求出：

$Area=\frac{a+b}{2}h$

a =基数
b =基数
h =高度
例子 ：

Input : base1 = 8, base2 = 10, height = 6
Output : Area is: 54.0

Input :base1 = 4, base2 = 20, height = 7
Output :Area is: 84.0

C++

// C++ program to calculate
// area of a trapezoid
#include
using namespace std;
 
// Function for the area
double Area(int b1, int b2,
                    int h)
{
    return ((b1 + b2) / 2) * h;
}
 
// Driver Code
int main()
{
    int base1 = 8, base2 = 10,
                height = 6;
    double area = Area(base1, base2,
                            height);
    cout << "Area is: " << area;
    return 0;
}
