Answer:

Answer: 132.93 cm²

Explanation:

• If you see the composite figure, it is made up of two quarter circles and one rectangle.

Area of two quarter circles :


{ \tt{area \: of \: quarter \: circle = (1)/(4) \pi {r}^(2) }} \\

  • r is radius, radius is 7 cm


{ \tt{area \: of \: two \: quarter \: circles = 2( (1)/(4)\pi {r}^(2) ) }} \\ \\ = { \tt{ (1)/(2) \pi {r}^(2) }} \\ \\ { \tt{ = (1)/(2) * 3.14 * {7}^(2) }} \\ \\ { \underline{ \tt{ \: = 76.93 \: {cm}^(2) \: }}}

Area of rectangle :


{ \tt{area = length * width}} \\{ \tt{area = 8 * 7}} \\ { \underline{ \tt{ \: area = 56 \: {cm}^(2) \: }}}

Area of composite figure :


{ \tt{area = 76.93 + 56}} \\ { \underline{ \underline{ \tt{ \: \: area = 132.93 \: {cm}^(2) \: \: }}}}
