Respuesta:

As = 36( 4 - π ) cm²

Explicación paso a paso:

El área sombreada sera:

As = Area del Cuadrado - 4 circunferencias

Desarrollo:

$As = {(12 \: cm)}^{2} - 4\pi {(3 \: cm)}^{2} \\ As = 144 \: {cm}^{2} \: - 4\pi9 \: {cm}^{2} \\ As = 144 \: {cm}^{2} \: - 36\pi\: {cm}^{2} \\ As = 36(4 - \pi) {cm}^{2}$
