Question

quanto vale um triangulo com √3 cm de altulra e √12cm de largura?

Answer 1

Quer a área do triângulo que tem base √12 e altura √3?

$A_{tri\^angulo}=\dfrac{base*altura}{2}\\\\\\A_{tri\^angulo}=\dfrac{\sqrt{12}*\sqrt{3}}{2}\\\\\\A_{tri\^angulo}=\dfrac{\sqrt{12*3}}{2}\\\\\\A_{tri\^angulo}=\dfrac{\sqrt{36}}{2}$

$A_{tri\^angulo}=\dfrac{6}{2}\\\\\\\boxed{\boxed{A_{tri\^angulo}=3~cm^{2}}}$
