Question

Me ajudem por favor????​

Answer 1

Resposta:

288√3 m²

Explicação passo a passo:

$A=\frac{3.l^{2}\sqrt{3} }{2} \\\\l=8\sqrt{3} \\\\\\\\A=\frac{3.(8\sqrt{3} )^{2}\sqrt{3} }{2} \\\\A=\frac{3.8^{2} (\sqrt{3} )^{2}\sqrt{3} }{2} \\\\A=\frac{3.64 .3\sqrt{3} }{2} \\\\A=\frac{9.64\sqrt{3} }{2} \\\\A=9.32\sqrt{3}\\\\A=288\sqrt{3}$
