The two straight edges of the shape correspond to the original circle's radius, 5.5 cm. We're told this sector has area 30.25 cm^2, which we will use to determine the measure of the central angle subtended by the arc (the remaining edge of the shape).
The complete circle has an area of 
, which corresponds to a "central angle" of 
. Then if 
is the central angle of this sector, we have
The complete circle has a circumference of 
. Then if 
is the length of the sector's arc, we get
So the sector has a total perimeter of
5.5 cm + 5.5 cm + 11 cm = 22 cm
Try the lowest option first. 8 is not divisible by 3 so you can rule out D. The next lowest option is 24. 24 is divisible by all 4 numbers so that it is the answer.
