多边形和矩形的面积 [英] Area of Polygon-triangle and rectangle

问题描述

嘿，我有一个问题

用C#编写程序以使用多个构造函数查找多边形，三角形和矩形的面积?

这是我的答案

Hey I have a question

Write a program in C# to find the area of polygon, triangle and rectangle by using multiple constructors?

and here is my answer

class Area
{
    public Area(double x, double y)
    {
        double res = .5 * x * y;
        Console.WriteLine("Area of triangle "+res);
    }

    public Area(int x, int y)
    {
        int res = x * y;
        Console.WriteLine("Area of Rectangle "+res);
    }

    static void Main(string[] args)
    {
        Area obj = new Area(20.50, 50.10);
        obj = new Area(10,10);
        Console.ReadLine();
    }
}

但是我不知道实现多边形以及如何找到它的区域.


我从Given Link获得了解决方案，但无法理解第一个构造方法
答案 [

but I have no idea about implementing polygon and how to find it area.


I got Solution from Given Link but I unable to understand first Constructor Method

please Help me.

推荐答案

稍作谷歌搜索就能回答您的问题:

A little googling would have answered your question:

public class Area
{
    public static double AreaPolygon(int[] x, int[] y, int noOfPoints)
    {
        double area = 0;
        for (int i = 0; i < noOfPoints; i++)
        {
            area = area + ((x[i] * y[i+1]) - (x[i + 1] * y[i]))
        }
        area = area * 0.5;
        return area;
    }

    public static double AreaTriangle(int b, int h)
    {
        return (b * h) * 0.5;
    }

    public static double AreaRectangle(int l, int h)
    {
        return (l * h);
    }
}
