Answer:
<em><u>1 and 5</u></em>
Step-by-step explanation:
The squares have a side length of 10 and 1 square side is the radius of the half-circles. Since there are two half-circles, find the circumference for one full circle:
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
Insert the radius:
![r=10\\C=2\pi *10](https://tex.z-dn.net/?f=r%3D10%5C%5CC%3D2%5Cpi%20%2A10)
Simplify pi:
![C=2*3.14*10](https://tex.z-dn.net/?f=C%3D2%2A3.14%2A10)
Simplify multiplication:
![C=6.28*10\\C=62.8](https://tex.z-dn.net/?f=C%3D6.28%2A10%5C%5CC%3D62.8)
The circumference of the circles is 62.8. Now find the perimeter of the exposed squares with side length 10. There are 4 exposed sides, which equals one square. Find the perimeter:
![P=10+10+10+10\\P=10+10+20\\P=10+30\\P=40](https://tex.z-dn.net/?f=P%3D10%2B10%2B10%2B10%5C%5CP%3D10%2B10%2B20%5C%5CP%3D10%2B30%5C%5CP%3D40)
Add the perimeter of the circle and the square together:
![P=62.8+40=102.8](https://tex.z-dn.net/?f=P%3D62.8%2B40%3D102.8)
Now see which of the options gives you the perimeter:
