Respuesta :
Total number of elements in an array = the number of rows * number of columns
Let number of rows be = x
[tex]18=2x[/tex]
As given, there are 2 columns and 18 objects so number of rows will be
x =[tex]\frac{18}{2}=9[/tex]
Hence, there are 9 rows and 2 columns.
Using proportions, it is found that:
- The array has 2 columns.
- The array has 9 rows.
For every row, there are 2 columns, thus, the number of columns in the array is 2.
In total, there are 18 objects, 2 in each column. Applying the proportion, the number of rows is:
[tex]r = \frac{18}{2} = 9[/tex]
Thus, there are 2 columns and 9 rows in the array.
