#include <iostream>
using namespace std;
int main(){
    int a,b,s,c;
    cin >> a >> b;
    c = (a + b) * 2;
    s = a * b;
    cout << c << endl << s;
    return 0;
}

using namespace std;
int main()
{
    int a,b;
    cin >> a >> b;
    cout << 2 * (a + b) << endl << a * b << endl;
}

只需8行~

a = [int(i) for i in input().split()]
b = a[0] + a[1]
b = b * 2
c = a[0] * a[1]
print(b)
print(c)
