Explanation:
To inscribe means to draw inside a figure so as to touch in as many places as possible without overlapping. The circle is inside the square such that the diameter of the circle is the same as the side of the square, so the side is actually 4 in.
The perimeter of the square = 4s = 4 × 4 = 16in.
