i have a final question, which is how do i find this. i know what the question is askin i just dont understand how to get the answer

Two planets A and B, where B has twice the

mass of A, orbit the Sun in elliptical orbits.

The semi-major axis of the elliptical orbit of

planet B is two times larger than the semi-

major axis of the elliptical orbit of planet A.

What is the ratio of the orbital period of

planet B to that of planet A?
