Answer:  If the rows must be even, she can set

14 rows of 5 chairs

10 rows of 7 chairs

7 rows of 10 chairs  or

5 rows of 14 chairs

Step-by-step explanation:

Take the prime factors of 70: 2, 5 and 7  Multiply  them in different ways to get the combinations where no product is greater than 20. (7 ×5 is the one combination of factors that won't work)
