Question

Me ajudem por favor nessa questão??!!!​

Answer 1

Resposta:

288√3 m²

Explicação passo a passo:

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

Answer 2

$A = \frac{3.l^{2}.\sqrt{3} }{2} \\A = \frac{3.(8\sqrt{3} )^{2}.\sqrt{3} }{2} \\A = \frac{3.(8\sqrt{3})(8.\sqrt{3} ).\sqrt{3} }{2} \\A = \frac{3.(64\sqrt{9}).\sqrt{3} }{2} \\ A = \frac{3.64.3\sqrt{3} }{2} \\A = \frac{3.64.3\sqrt{3} }{2} \\A = \frac{576.\sqrt{3} }{2} \\A= 288\sqrt{3}$
