Answer:
P = 78 cm
Explanation:
note that the 4 sides of the polygon are tangents to the circle.
Tangents to a circle from an external point to the circle at the point of contact with the circle are congruent.
then summing the tangents, starting with the lower side, and counting anti- clockwise, the perimeter (P) is
P = 6 + 9 + 9 + 16 + 16 + 8 + 8 + 6 = 78 cm
