Question

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 perpendcular distance between the parallel sides) 

Answer 1

import java.util.*;
class FQ15{
static void Area(float b, float h)
{double tmp = b * h;
System.out.println("Area =" + tmp);
}
static void Area(double d1, double d2)
{double a = 1.0 / 2 * d1 * d2;
System.out.println("Area  = " + a);
}

static void Area(double a, double b, double h)
{double t = 1.0 / 2 * (a + b) * h;
System.out.println("Area = " + t);
}

public static void main(String jK[])
{ Scanner ob = new Scanner(System.in);
double a, b, h;
System.out.println("\nEnter the breadth,height of the parallelogram");
Area(ob.nextFloat(),ob.nextFloat()); // METHOD CALL
System.out.println("\nEnter diagonal 1,diagonal 2 for the rhombus");
Area(ob.nextDouble(),ob.nextDouble()); // METHOD CALL
System.out.println("\nEnter the parallel sides a, b");
a = ob.nextDouble();
b = ob.nextDouble();
System.out.printIn("Enter the perpendicular distance between the parallel sides");
h = ob.nextDouble();
Area(a, b, h); // METHOD CALL
