Answer 1

public class Rectangle {
    private int left;
    private int bottom;
    private int width;
    private int height;

    public Rectangle(int left, int bottom, int width, int height) {
        this.left = left > 0 ? left : 0;
        this.bottom = bottom > 0 ? bottom : 0;
        this.width = width > 0 ? width : 0;
        this.height = height > 0 ? height : 0;
    }


    @Override
    public String toString() {
        return "base:(" + left + "," + bottom + ") w:" + width + " h:" + height;
    }

    public int area() {
        return width * height;
    }

    public int perimeter() {
        return 2 * (width + height);
    }

    public static Rectangle intersection(Rectangle a, Rectangle b) {
        int xALeft = a.left;
        int xARight = a.left + a.width;
        int yATop = a.bottom + a.height;
        int yABottom = a.bottom;

        int xBLeft = b.left;
        int xBRight = b.left + b.width;
        int yBTop = b.bottom + b.height;
        int yBBottom = b.bottom;

        if (xBLeft > xARight || xALeft > xBRight || yABottom > yBTop || yBBottom > yATop) {
            return new Rectangle(0, 0, 0, 0);
        } else {
            int left = Math.max(xALeft, xBLeft);
            int right = Math.min(xARight, xBRight);
            int bottom = Math.max(yABottom, yBBottom);
            int top = Math.min(yATop, yBTop);
            return new Rectangle(left, bottom, right - left, top - bottom);
        }
    }

    public static int totalPerimeter(Rectangle a, Rectangle b) {
        return a.perimeter() + b.perimeter() - intersection(a, b).perimeter();
    }

    public boolean contains(Rectangle rectangle) {
        return left <= rectangle.left && left + width >= rectangle.left + rectangle.width &&
                bottom <= rectangle.bottom && bottom + height >= rectangle.bottom + rectangle.height;
    }
}
