Question

Amanda wants 2 rows of tomato plants in her garden. Make sketches to show your thinking. Can Amanda make an array with 2 equal rows if she has: 9 tomato plants?12 tomato plants?14 tomato plants?15 tomato plants?

Answer 1

12 tomato plants

14 tomato plants12 tomato plants

14 tomato plants

Step-by-step explanation:

If Amanda wants 2 rows of tomato plants, this is possible if the number of tomato plants is exactly divisible by 2.

`\begin{gathered} (12)/(2)=6\text{ plants per rows} \\ (14)/(2)=7\text{ plants per rows} \end{gathered}`

However, 9 and 15 are not exactly divisible by 2.

Thus, Amanda can only make an array with 2 equal rows if she has 12 and 14 tomato plants.
