Answer 1

Explicación paso a paso:

Donde:

S = Region sombreada

9.

S = 1/2 (A. Cuadrado)

$S = \frac{ {(4 \: u)}^{2} }{2} \\ S = \frac{16 \: {u}^{2} }{2} \\ \boxed{ S = 8 \: {u}^{2} }$

10.

S = (A. Cuadrado) - 1/4 (A. circunferencia)

$S = {(8 \: u)}^{2} - \frac{1}{4} \pi {(8 \: u)}^{2} \\ S = 64 \: {u}^{2} - \frac{64 \: {u}^{2} }{4} \pi \\ S = 64 \: {u}^{2} - 16\: {u}^{2}\pi \\ \boxed{S = 16(4 - \pi){u}^{2} }$

11.

S = (A. Rectangulo) - (A. Rombo)

$S = (12 \: u)(5 \: u) - \frac{1}{2} (4 \: u)(5 \: u) \\ S = 60 \: {u}^{2} - \frac{20 \: {u}^{2} }{2} \\ S = 60 \: {u}^{2} - 10 \: {u}^{2} \\ \boxed{S = 50 \: {u}^{2} }$
