Answer 1

Area of shaded region=Area of triangle - Area of 3 Arcs.

$area \: of \: triangle = \frac{ \sqrt{3} }{4} {a}^{2} \\ a = 8cm \\ = \frac{ \sqrt{3} }{4} \times 64 \\ = 16 \sqrt{3}$
$area \: of \: arc = \frac{\pi}{4} {r}^{2} \\ r = 4 \\ \\ = \frac{\pi}{4} {(4)}^{2} \\ 4\pi$
Area of arc=4π

➡️Area of 3 arcs=12π

$<b>$Now area of shade portion=16√3-12π
