$\small\text{Angolo minore al vertice \(= \dfrac{45}{2+3}×2 = \dfrac{45}{5}×2 = 18°;\)}$
$\small\text{angolo maggiore al vertice \(= \dfrac{45}{2+3}×3 = \dfrac{45}{5}×3 = 27°;\)}$
$\small\text{altezza \(h= \dfrac{3}{tan(27°)} \approx5,888\,u;\)}$
$\small\text{area triangolo a sinistra \(A_1= \dfrac{\cancel2×5,888}{\cancel2} = 5,888\,u^2;\)}$
$\small\text{area triangolo a destra \(A_2= \dfrac{3×5,888}{2} = 8,832\,u^2;\)}$
$\small\text{area triangolo totale \(A_{tot}= 5,888 + 8,832 = 14,72\,u^2;\)}$
