Answer 1

$area \: of \: square = {(side)}^{2} \\ area \: of \: circle = \pi {r}^{2} \\ are \: of \: semi \: circle = \frac{\pi {r}^{2} }{2} \\ \\ \\ i) side = 10.5 \: cm\\ area \: of \: square = {(10.5)}^{2} \\ = 110.25 \: {cm}^{2} \\ \\ ii) \\ r = 3.5 \: cm \\ area \: of \: circle = \frac{22}{7} \times {3.5}^{2} \\ \\ = 38.5 \: {cm}^{2} \\ \\ \\ iii) \\ r = 4.9 \: cm \\ \\ area \: ofsemi \: circle = \frac{ \frac{22}{7} \times {4.9}^{2} }{2} \\ = 37.73 \: {cm}^{2} \\ \\ iv) \\ side = 6.1 \: cm \\ area \: of \: square = {(6.1)}^{2} \\ = 37.21 \: {cm}^{2} \\ \\ v) \\ d = 12.6 \: m \\r = 12.6 \div 2 = 6.3 \: cm \\ area \: of \: circle = \frac{22}{7} {(6.3)}^{2} \\ = 124.74 \: {cm}^{2}$
