Hints

Read two numbers with sc.nextInt().

Put the maths in brackets when you join it to text: "Area: " + (w * h).

Solution explanation

Without brackets, "Area: " + w * h still works because * goes first, but "P: " + 2 * (w + h) is clearer with brackets around the whole sum.

Show solution

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int w = sc.nextInt();
        int h = sc.nextInt();
        System.out.println("Area: " + (w * h));
        System.out.println("Perimeter: " + (2 * (w + h)));
    }
}
