Hi dear
here is your answer

Answer 2

Answer:

$\red {Area \:of \:the \:shaded \:region }$

$\green {= 124.21 \:cm^{2}}$

Step-by-step explanation:

$Area \:of \:the \:shaded \:region \\= Area \:of \: semicircle \\+ Area \:of \:the \: rectangle\\ - area \:of\:triangle$

$= \pi \times \frac{d^{2}}{8} + l \times b - \frac{1}{2} \times base \times altitude$

$= \frac{22}{7} \times \frac{10^{2}}{8} + 10\times 10 - \frac{1}{2} \times 8 \times 6 \\= 48.21+100-24\\=124.21 \:cm^{2}$

Therefore.,

$\red { Area \:of \:the \:shaded \: region }$

$\green {= 124.21 \:cm^{2}}$
