Question

GUYS HELPPPP PLEASE I RLY NEED IT RN, I NEED ANSWER #7 IM DESPERATE RN PLSSS

Answer 1

Answer:

6 units

Step-by-step 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!
