        int squareLength, squarePerimeter, squareArea;
        System.out.print("Enter Square Side Length: ");
        squareLength = input.nextInt();
        squarePerimeter = squareLength * 4;
        squareArea = squareLength * squareLength;
        System.out.println("Square Perimeter = " + squarePerimeter +
                "nSquare Area = " + squareArea);
    }
