Okay.. let's see if you were correct as we go along.

Now, this shape has two figures:
1. A semi circle

yeah okay

Answer 6

You need to find the perimeter of each individual shape then add them together.

Answer 7

What is the perimeter of the square?

Correct! Now, we can immediately eliminate C and D because the perimeter of the total figure will be GREATER than 16 since we haven't figured out the perimeter of the circle yet.
