I think the answer is x=60
Perimeter is when you add all the sides together...but oh, no! There are two sides missing! So we have to find it. The horizontal like could be x and the vertical, the y. x would be 3 because one side is 7 and the other side is 4, so if we subtract them, we get 3. Same for the vertical, the y would be 3. (3+3=6)
Now we could add all sides to get the last choice, or 26 cm.

Answer:
(x + 2)² + (y + 7)² = 9
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r the radius
Here (h, k) = (- 2, - 7) and r = 3, thus
(x - (- 2))² + (y - (- 7))² = 3², that is
(x + 2)² + (y + 7)² = 9
