Answer: 223 days
Step-by-step explanation:
From Kepler's third law, the orbital period of planet around the sun is related with the semi-major axis of the orbit as:
p² = a³
where p is the orbital period in years and a is the semi-major axis/ distance to the star in AU.
It is given for Venus, a = 0.72 AU, then
p = √(0.72 AU)³ = 0.61 years
1 year = 365 days 222.9 days ≈ 223 days
