Confused with premiter

Answer 1

The area will be, the area of the semi circle plus the area of the rectangle:

For the rectangle:

`\begin{gathered} Ar=l\cdot w \\ Ar=10\cdot4=40in^2 \end{gathered}`

For the semicircle:

`\begin{gathered} As=\frac{\pi r^2_{}}{2} \\ As=(25\pi)/(2) \end{gathered}`

Therefore:

`\begin{gathered} A=Ar+As \\ A=40+(25\pi)/(2) \\ A\approx79.27in^2 \end{gathered}`
