Answer 2

Answer: Option 'C' is correct.

Explanation:

Since we know that

The figure is known as "Quadrant" in which angle is 90° .

As we know that "Length of an arc":

`Length=(\theta)/(360\textdegree)* 2* 3.14* r\\\\Length=(90\textdegree)/(360\textdegree)* 2* 3.14* 2\\\\Length=(1)/(4)* 12.56\\\\Length=3.14`

Perimeter of the figure is given by

`3.14+2+2=7.1`

Hence, Option 'C' is correct.
