Answer:

6 units

Explanation:

The questions states that the area = perimeter.

From this we can set up an equation:


x*y=2x+2y

Since we know one of the sides is 3 we can substitue one of the variables for 3. In this case I choose
y


3*x=2x+2*3\\3x=2x+6

Solving for x we get
x=6.

That's our answer!
