Answer:
113 (d)
Step-by-step explanation:
Since the room is square-shaped, you square root the area (12,769) to find the length of each wall. You will get the answer 113. To check this answer multiply 113 by 113 and make sure you get the correct area; it works, so you know the answer is D.
The formula for the circumference is 2πr.
Radius is half of the diameter which comes out to be 13.
2 x π x 13 = 81.6
Hope this helps!
