The trigonometric parallax gives $d=1/0.02=50\mathrm{pc}$. Neglecting extinction, the distance modulus and given bolometric correction giveUsing the specified solar bolometric magnitude,The mass estimate uses the cubic scaling normalized to solar values. A lifetime estimate additionally needs the fraction of fuel accessible to core burning. Take a core-accessible fraction $f_c=0.1$ and initial hydrogen mass fraction $X=0.7$. The supplied fusion energy givesThe alternative common solar-lifetime normalization $t\simeq 10^{10}(M/M_{\odot })/(L/L_{\odot })$ years gives $1.69\times 10^9$ years. Thus this simplified turnoff argument gives an age of order $10^9$ years, with its fuel fraction and mass-luminosity assumptions explicitly stated. It does not use a modern fitted Hyades age or a full stellar isochrone. Unresolved binaries, extinction and deviations from the homology law affect the estimate.

The parallax gives $d=1/0.00763\simeq 131\mathrm{pc}$. Ignoring extinction, the distance modulus givesThe bolometric magnitude relation then yields $L/L_{\odot }=10^{0.4(4.72-M_{\mathrm{bol}})}\simeq 2.53\times 10^4$. With $T_{\odot }\simeq 5772\mathrm{K}$,A star this cool and luminous belongs to the red-supergiant region of the Hertzsprung-Russell diagram. Extinction and the adopted effective temperature are important systematic inputs; this calculation uses the supplied temperature to infer the radius.
