Answer:
C
Step-by-step explanation:
1. π ≈ 3.1415. π + 10 ≈ 13.1415.
2. Find the square root of 20. It is about 4.4721. 4.4721 + 1/2 (or .5) = 4.9721
3. The square root of 100 is 10.
4. Order them.
5. It is most obvious that the answer to + 1/2 is first. The square root of 100 is ten, so that goes second because pi + 10 is greater than 10. (pi + 10 goes last)

Step-by-step explanation:
A square's diagonal cuts across the square, making two right triangles where the diagonal is the hypotenuse.
We have a right triangle with a hypotenuse of 29, and two legs that are the same length (because they are sides of a square)
So, we can use pythagoreans theorem to find the lengths of the legs, or sides of the square.
Now that we have a side length of , we just have to multiply that by 4, since a square has 4 sides. This leaves us with a final perimeter of:
