hi, please help a sis out :))

Answer:
The value of x is 16 and the width is 4.
Step-by-step explanation:
The area of a rectangle is the length multiplied by the width, which is [tex]9\sqrt{x}[/tex].
So, [tex]9\sqrt{x}[/tex] = 36.
We divide both sides by 9, getting [tex]\sqrt{x}[/tex] = 4.
We then square both sides, getting x = 16.
The value of x is 16, and the width is 4.
