Question

determine a area do triangulo a seguir 4m, 4m, 4m

Answer 1

Lados iguais, equilátero

A = ( L^2√3) / 4 

A = ( 4^2√3 ) / 4

A = 16√3 / 4

A = 4√3 cm^2

Answer 2

$a = \frac{(l^{2} \sqrt{3} )}{4} \\ \\ a = \frac{(4 ^{2} \sqrt{3}) }{4} \\ \\ a = \frac{16 \sqrt{3} }{ 4 } \\ \\ a = 4 \sqrt{3} cm^{2}$
