Answer:
The correct option is D.
Step-by-step explanation:
The area of a square with side s is defined as
[tex]A=s\times s[/tex]
[tex]A=s^2[/tex] .... (1)
The given expression is
[tex]A=(6x)^2[/tex] .... (2)
From (1) and (2), we get
[tex]s=6x[/tex]
It means the expression [tex](6x)^2[/tex] represents the area of a square with a side length of 6x .
Therefore the correct option is D.
