--------------------------------------------------------------------------- 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
