Make them into a square. If you were to make the lines all go the same way, you would need 20 dots to make four rows of five, but if you put them in a square shape, the dots in the corners occur in two lines (ones going across and ones going down), like this: O O O O O O O O O O O O O O O O Four rows of five!
Write down 4 rows of 3 dots or 3 rows of 4 dots.

The answer is to arrange them into a five pointed star. See http://www.puzzles.com/PuzzlePlayground/10in5Rows/10in5RowsSol.htm for an illustration of the solution.
a star drawn with five lines will give you 10 dots on 5 lines with only 4 dots on each line. (or) simply draw a pentagon and put a cap ( a inverted 'V') on all sides.
There are a total of 2,000 dots on a 50 by 40 array page. This can be calculated by multiplying the number of rows (50) by the number of columns (40).
1 row of 100 chairs. 2 rows of 50 chairs. 4 rows of 25 chairs. 5 rows of 20 chairs. 10 rows of 10 chairs. 20 rows of 5 chairs. 25 rows of 4 chairs. 50 rows of 2 chairs. 100 rows of 1 chair. Or you could put them all in one big circle.
4(x + 12) ≤ 16
Put a small pentagon inside a larger pentagon...
