Answer:

P = 46cm

Explanation:

If the circle inscribed in a quadrilateral, then the sums of the opposite sides of the quadrilateral are the same.

Therefore we have the equation:

AB + CD = BC + AD

Therefore the perimeter of polygon ABCD is equal to

P = 2(AB + CD)

Substitute AB = 10.5cm, CD = 12.5cm:

P = 2(10.5cm + 12.5cm) = 2(23cm) = 46cm
