Answer:

The array has 9 rows and 18 columns.

Explanation:

Let the number of rows of the array = x

Then, the number of columns = 2x

The division sentence that describes this situation is:

(2x)/(2) =x

Here, the dividend is 2x.

But, it is given that the dividend is 18.

So, 2x = 18 and

(2x)/(2) =(18)/(2)

x = 9

Hence, the array has 9 rows and 18 columns.
