The heat transfer from a single fin of the figure will be calculated using the adiabatic tip with corrected length approach. It is known that

The fin is made from aluminum

$x=3\mathrm{.}2mm$

$Y=31cm$

$Z=4\mathrm{.}0cm$

$T_b=88C$

$T_{}=30C$

$h=28\frac{W}{m^2(K)}$

Calculate the parameter $P\{$fin$\text{'}$s perimeter$),$ in meters. Use $4$ decimal places in your answer.
