Answer:
Explanation:
False.
A 6 by 7 array is a rectangular array with 6 rows and 7 columns. In order for an array to model a square number, it must have the same number of rows and columns, forming a perfect square. For example, a 5 by 5 array or a 8 by 8 array would model a square number.
Therefore, since a 6 by 7 array is not a square, it does not model a square number.
