Answer:

[tex]58.8\ mm^{2}[/tex]

Step-by-step explanation:

we know that

The area of the figure is equal to the area of a rectangle plus the area of semicircle

Step 1

Find the area of the rectangle

The area of the rectangle is equal to

[tex]A=bh[/tex]

we have

[tex]b=9\ mm[/tex]

[tex]h=3\ mm[/tex]

substitute

[tex]A=9*3=27\ mm^{2}[/tex]

Step 2

Find the area of semicircle

The area of semicircle is equal to

[tex]A=\frac{1}{2}\pi r^{2}[/tex]

we have

[tex]r=9/2=4.5\ m[/tex]

substitute

[tex]A=\frac{1}{2}(3.14)(4.5^{2})=31.8\ mm^{2}[/tex]

Step 3

Find the area of the figure

[tex]27\ mm^{2}+31.8\ mm^{2}=58.8\ mm^{2}[/tex]
