Answer: The length of AB is 2 units.

Step-by-step explanation: We are given that the trapezoid ABCD is an isosceles one, where

AB = 2x, BC = 2x + 2 and AD = 4 units.

We are to find the length of side AB of the trapezoid.

We know that

in an isosceles trapezoid, the lengths of two non parallel sides are equal.

So, in ABCD, we have


AD=BC\\\\\Rightarrow 4=2x+2\\\\\Rightarrow 2x=2\\\\\Rightarrow x=1.

Therefore, the length of AB will be


AB=2x=2*1=2~\textup{units}.

Thus, the length of AB is 2 units.
