Calculating Areas Of Geometric Shapes

Write a class that has three overloaded static methods for calculating the areas of the
following geometric shapes:

• circles -- area = π*radius^2 (format the answer to have two decimal places)
• rectangles -- area = width * length
• trapezoid -- area = (base1 + base2) * height/2

Because the three methods are to be overloaded, they should each have the same name , but different parameters (for example, the method to be used with circles should only take one parameter , the radius of the circle).

Demonstrate the methods in a program that prints out the following areas, each on a separate line:

• the area of a circle with radius 3
• the area of a rectangle with length 2 and width 4
• the area of a trapezoid with base lengths 3 and 5 and height 5

public static double area(double radius)
{
return (double)(Math.PI*Math.pow(radius,2));
}
public static int area(int length, int breadth)
