Answer:

The array has 9 rows and 18 columns.

Step-by-step explanation:

Let the number of rows of the array = x

Then, the number of columns = 2x

The division sentence that describes this situation is:

[tex]\frac{2x}{2} =x[/tex]

Here, the dividend is 2x.

But, it is given that the dividend is 18.

So, 2x = 18 and

[tex]\frac{2x}{2} =\frac{18}{2}[/tex]

x = 9

Hence, the array has 9 rows and 18 columns.
