Based on the information given, we know that BD = DF = 16, because B, D, and F are midpoints of the sides of triangle ACE.

Since B and D are midpoints of AC and CE respectively, we can conclude that AB = BC = CD = DE = EF, because midpoints of a triangle's sides divide the sides into segments of equal length.

Therefore, AB = BC = CD = DE = EF = 16.

Since AC = AB + BC, we can substitute the value of AB and BC, which is 16, into the equation.

AC = 16 + 16 = 32.

Therefore, AC = 32.
