Answer 1

Resposta:

39.1.

$A_{adc}=\frac{b.h}{2}\\A_{adc}=\frac{4.1}{2}\\A_{adc}=2\mu^2$

$A_{adc}=A_{abc}$

$A_{abcd}=A_{adc}+A_{abc}\\A_{abcd}=2+2\\A_{abcd}=4\mu^2$

39.2

$A_{adc}=\frac{b.h}{2}\\A_{adc}=\frac{4.3}{2}\\A_{adc}=6\mu^2$

$A_{adc}=A_{abc}$

$A_{abcd}=A_{adc}+A_{abc}\\A_{abcd}=6+6\\A_{abcd}=12\mu^2$
