Answer:
24.997
Step-by-step explanation:
Let's start with the easy parts of the perimeter...the flat parts...7 + 7 = 14. We'll add that to the arch shortly.
We need to find the circumference of the whole circle, then divide by 4 to get 1/4 of a circle. (There might be a faster way, but this gets the job done.)
circumference = (2)(pi)(r)
= 2(3.142)(7) = 43.988
Now divide that by 4 for the distance of the arch.
43.988/4 = 10.997
Add that to the flat parts
10.997 + 14 = 24.997
