Answer:
The perimeter of the figure is approximately 42.85.
Step-by-step explanation:
Based on the given values, you already know that two of the sides of the shape are 12 units long. Since the half-circle above the rectangle is the same size as the gap in the rectangle - you know this because both of the half-circle's diameter are 6 units long - so you can add 24 units to the perimeter of a circle with a diameter of 6. The diameter of the circle is 
, or approximately 18.85, so the perimeter of the whole figure is approximately 42.85.
A question like this should be answered by first looking at the number and the numbers you are given and making an estimate, testing it, and repeating if it is incorrect. It is relatively simple and I would like you to at least try a couple of times with an estimate of your own. If you really do have trouble with this, I will put the answers in a second. To make sure you understand the concept I will answer 3 of the 4 and you can try the last one. I will also just state the number of steps and leave the most of the expression writing to you. ;)
A. 8 feet forward, 8 feet forward. 8×2 or 0 + 8 + 8
B. Probably the hardest. Good thing you get to do it :)
C. 6 feet forward, 5 feet forward. 0 + 6+5 or 0 + 5+6 (This shows the commutative property)
D. 8 feet forward, 5 feet back. 0 + 8 - 5 or 0 - 5 + 8.
(You Don't Need the 0's in any of them unless you are showing the starting point which you probably are required to do, but since technically the Cecil starts at 0, added the 0 as the point at which to start your expression.)
