Answer 1

Answer:

$344 {cm}^{2}$

Step-by-step explanation:

$area \: of \: the \: square \\ = 40cm \times 40cm \\ = 1600 {cm}^{3}$

$area \: of \: the \: circle \\ = \pi {r}^{2} \\ = 3.14 \times {(20)}^{2} \\ = 3.14 \times 400 \\ = 1256 {cm}^{2}$

$area \: of \: shaded \: region \\ = 1600 {cm}^{2} - 1256 {cm}^{2} \\ = 344 {cm}^{2}$
