Question:

Write a class that has three overloaded static methods for calculating the areas of the following geometric shapes: circles -- area = *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
