Question

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

Answer 1

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!
