Find missing length (opposite of 20cm below the quarter)
---------------------------------------------------------------------------
20 cm = 11 cm = 9 cm
---------------------------------------------------------------------------
Find the quarter arc
---------------------------------------------------------------------------
Perimeter of the quarter arc = [tex] \frac{1}{4} \pi D[/tex]
Perimeter of the quarter arc = [tex] \frac{1}{4} \pi (2 \times 11)[/tex]
Perimeter of the quarter arc = 17.28 cm (nearest hundredth)
---------------------------------------------------------------------------
Find Perimeter of the figure
---------------------------------------------------------------------------
* Add them up clockwise
Perimeter = 20 + 2 + 17.28 + 11 + 9 + 2
Perimeter = 61.28 cm
---------------------------------------------------------------------------
Answer: 61.28cm
