| If it was possible to inscribe a circle into the quadrangle ABCD, then the following condition must be met:
AB + CD = BC + AD (the sums of the opposite sides must be equal).
AB + CD = 10 + 16 = 26;
BC + AD = 26.
Find the perimeter of the quadrangle:
(AB + CD) + (BC + AD) = 26 + 26 = 52.
Answer: 52.
