Answer:
[tex]37.55\ m[/tex]
Step-by-step explanation:
we know that
The perimeter of the figure is equal to the perimeter of semicircle plus the perimeter of quarter circle plus two times the length of [tex]2\ m[/tex] plus two times the length of [tex]5\ m[/tex]
Find the perimeter of semicircle
we know that
The circumference of a semicircle is equal to
[tex]C=\frac{1}{2}\pi D[/tex]
we have
[tex]D=10\ m[/tex]
substitute
[tex]C=\frac{1}{2}\pi(10)=5 \pi\ m[/tex]
Find the perimeter of a quarter of circle
we know that
The circumference of a quarter of circle is equal to
[tex]C=\frac{1}{4}\pi D[/tex]
we have
[tex]D=10\ m[/tex]
substitute
[tex]C=\frac{1}{4}\pi(10)=2.5 \pi\ m[/tex]
Find the perimeter of the figure
[tex]5 \pi\ m+2.5 \pi\ m+2*2\ m+2*5\ m=7.5 \pi\ m+14\ m[/tex]
[tex]7.5 \pi+14=37.55\ m[/tex]
