Lets figure out the given by the following steps:
Number of dots in each row = \(8\) dots
Number of rows = \(r\)
Therefore, number of dots = \(8r\)
When there are \(8\) rows,
then number of dots = \(8 \times 8\) = \(64\) dots
When there are \(10\) rows,
then number of dots = \(8 \times 10 = 80\) dots
So, the correct answer is: 80 dots.
