Answer 2

Answer:

10.5 cm^2

Step-by-step explanation:

Area of Shaded region = area of square - area of 2 semi-circles.

$area \: of \: shaded \: region \: = a {}^{2} - 2 \times \frac{\pi \: r {}^{2} }{2}$

$7 {}^{2} - \frac{22}{7} \times \frac{7}{2} \times \frac{7}{2}$

$49 - \frac{77}{2} = \frac{98 - 77}{2} = \frac{21}{7} = 10.5$
