Answer-


\boxed{\boxed{AC=8}}

Solution-

Triangle Midpoint Theorem-

The line segment connecting the midpoints of two sides of a triangle is parallel to the third side and is congruent to one half of the third side.

As given in the question,

AD = DB, so D is the mid point of AB,

FA = FC, so F is the mid point of AC.

Hence, DF is the line joining the midpoints of AB and AC.

Applying Triangle Midpoint Theorem,


\Rightarrow DF=(1)/(2)BC


\Rightarrow BC=2DF


\Rightarrow BC=2* 4


\Rightarrow BC=8

Therefore, the side length of BC is 8 units.
