Question

calcule a área de cada trapezio

Answer 1

$a)a = \frac{(base \: maior + base \: menor).altura}{2} \\ a = \frac{(7 + 4).6}{2} = \frac{11 \times 6}{2} = \frac{66}{2} = 33 \\ \\ c)a = \frac{(7+ 5).5}{2} = \frac{12 \times 5}{2} = \frac{60}{2} = 30 \\ \\ e)a = \frac{(10 + 6).2}{2} = \frac{16 \times 2}{2} = \frac{32}{2} = 16$
