In the absence of more detailed info, we'll have to assume that this illustration represents a quarter circle.

1.  What is the formula for the circumference of a circle of radius r?
2.  What is the formula for one fourth of the circumference of a circle?
3.  What is the length of one of the straight sides shown?
4.  What is the sum of the lengths of two of these sides?
5.  Put all this together.  What is the perimeter of the figure shown in the illustration?

To find the perimeter we would use the formula for circumference....we see that this is one-fourth of a circle so once we find the circumference we would divide it by `4` to find the perimeter of this....
