Write a class with the name Area using method overloading that computes the area of a parallelogram, a rhombus and a trapezium.

Formula:

Area of a parallelogram (pg) = base * ht

Area of a rhombus (rh) = (1/2) * d1 * d2
(where, d1 and d2 are the diagonals)

Area of a trapezium (tr) = (1/2) * ( a + b) * h
(where a and b are the parallel sides, h is the perpendicular distance between the parallel sides)

import java.util.Scanner;

public class Area
{
    public double area(double base, double height) {
        double a = base * height;
        return a;
    }
    
    public double area(double c, double d1, double d2) {
        double a = c * d1 * d2;
        return a;
    }
    
    public double area(double c, double a, double b, double h) {
        double x = c * (a + b) * h;
        return x;
    }
    
    public static void main(String args[]) {
        Scanner in = new Scanner(System.in);
