Explicação passo a passo:
[tex]\mathsf{A = \dfrac{6l^2\sqrt{3}}{4}}[/tex]
[tex]\mathsf{\dfrac{6l^2\sqrt{3}}{4} = 6\sqrt{3}}[/tex]
[tex]\mathsf{\dfrac{l^2}{4} = 1}[/tex]
[tex]\mathsf{l^2 = 4}[/tex]
[tex]\mathsf{l = 2}[/tex]
[tex]\mathsf{P = 6l}[/tex]
[tex]\mathsf{P = 6(2)}[/tex]
[tex]\boxed{\boxed{\mathsf{P = 12}}}\leftarrow\textsf{per{\'i}metro}[/tex]
