Question

calcule a area do triângulo ​

Answer 1

Resposta:

A = 20

Explicação passo-a-passo:

A = (b*h)/2

A = (5*8)/2

A = 40/2

A = 20

Answer 2

Área do triângulo

$\boxed{\boxed{\mathtt{A=\dfrac{b\times\,h}{2}}}}$

$\mathtt{A_{\triangle}=\dfrac{8.5}{2}}$

$\mathtt{A_{\triangle}=\dfrac{40}{2}}$

$\huge\boxed{\boxed{\mathtt{A_{\triangle} =20~{cm}^{2}}}}$
