Question

Determine a área de um triângulo cuja base mede 8 cm e a altura mede 5,2 cm.​

Answer 1

$\Large\boxed{\begin{array}{l}\sf A=\dfrac{1}{2}\cdot b\cdot h\\\\\sf A=\dfrac{1}{\diagdown\!\!\!\!\!2}\cdot\diagdown\!\!\!\!\!8^4\cdot5,2\\\\\sf A=4\cdot5,2\\\sf A=20,8~cm^2\end{array}}$

Answer 2

Resposta:

Área do triângulo = b.h/2

8 . 5,2 = 41.6 ÷ 2 = 20.8 cm^2
