For a P$-51$D calculate:

a$)$ The value of the root chord and tip chord in meters.

b$)$ The value of the angle of incidence of the profile that is at $65\%$ of the semi$-$span of the wing

c$)$ Considering that the wing is formed with the NACA $65(1)-212$ profile calculate the thickness

located at $67\%$ of the geometric mean chord and the camber at $50\%$ of the same chord
