Applying the distance between the points formula.

\(\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

The distance between the points (-9,-2) & (-1,-2) is \(\sqrt{(-1+9)^2+(-2+2)^2}\) = 8.

Similarly, for other points, we get the distance as 2,8 and 2.

Hence the perimeter is 8+2+8+2 = 20.

C is the answer.

It can solved faster by drawing points in co ordinate plane. By drawing, we will come to know that it is a rectangle with one side length=8 units, second side length=2 units.
Perimeter of rectangle= 2 x (l +b) = 2 x 10 = 20 which is answer C (Hit Kudos if my stated procedure helped you)
