look at the semicircle

area of semicircle


{ \boxed{ \bold{ \red{A = \pi \: * {r}^(2) }}}}


{ \bold{ \boxed{ \red{radius = (diameter)/(2) } }}}


radius = (8)/(2) = \boxed{4}


area = 3.14 * {4}^(2) \\ area = 50.24

as we can see that is a parallelogram

so ,

area of parallelogram


\boxed {\bold{ \red{area \: of \: parallelogram =b * h }}}


area \: = 8 * 10 \\ are \: = 80in

area of fig = area of semicircle + area of parallelogram

total area = 50.24+80

total area = 130.24 inĀ²


\boxed{130.24 {in}^(2) }
