Explicação passo a passo:

$\mathsf{a)\:A_B = a^2 \iff A_B = (3,5)^2 \iff A_B = 12.25\:u.a^2}$

$\mathsf{b)\:A_L = 4a^2 \iff A_L = 4.(3,5)^2 \iff A_L = 49\:u.a^2}$

$\mathsf{c)\:A_T = 6a^2 \iff A_T = 6.(3,5)^2 \iff A_T = 73,50\:u.a^2}$

$\mathsf{d)\:V = a^3 \iff V = (3,5)^3 \iff V = 42,88\:u.v^3}$

$\mathsf{e)\:D_B = a\sqrt{2} \iff D_B = 3,5\sqrt{2}\:u.c}$

$\mathsf{f)\:D_C = a\sqrt{3} \iff D_C = 3,5\sqrt{3}\:u.c}$
