//Write a program that allows the user to enter the width (w) and the height (h) of the rectangle
//and then calculates the perimeter and area of the rectangle. The program must check whether
//the width and the height is a positive number or not.
//Formula
//Perimeter = 2 * (w + h)
//Area = w * h
//Example 1: Please enter the width of the rectangle: -9
//Please enter the height of the rectangle: 3
//The edge of rectangle must be a positive number!
//Example 2: Please enter the width of the rectangle: 15
//Please enter the height of the rectangle: 0
//The edge of rectangle must be a positive number!
//Example 3: Please enter the width of the rectangle: 5
//Please enter the height of the rectangle: 12
//The perimeter of the rectangle is 34
//The area of the rectangle is 60
