When the semi-major axis a is in AU unit and the period is in Earth year, the period of any solar orbiter is a X sqrt (a). For Pluto, this is 248.065 years = (rounded to 4 sd) 248.1 years, nearly

Explanation:

This is only an approximation to the period, using Kepler's third (empirical) law for approximating the period..
