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:

Insert the radius:

Simplify pi:

Simplify multiplication:

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:

Add the perimeter of the circle and the square together:

Now see which of the options gives you the perimeter:
