class Rectangle:
    def __init__(self, w, h):
        self.w = w
        self.h = h

    def area(self):
        return self.w * self.h

    def perimeter(self):
        return 2 * (self.w + self.h)

    def is_square(self):
        return self.w == self.h


r = Rectangle(*map(int, input().split()))
print(r.area())
print(r.perimeter())
print(r.is_square())
