Question

observe atentamente a figura seguinte e calcule a area de cada polígono pedido

Answer 1

$a)A = \frac{b.h}{2} \\ \\ A = \frac{15.10}{2} = 75cm^2$


$b)A = l^2 \\ A = (6)^2 \\ A = 36cm^2$


$c)A = \frac{b.h}{2} \\ \\ A = \frac{6.4}{2} = 12cm^2$


$d) A = \frac{b.h}{2} \\ \\ A = \frac{6.6}{2} = 18cm^2$
