Final answer:
The correct formulas for finding the area of a square with side lengths of 9 are 9×9 and 9².
Step-by-step explanation:
The correct formulas for finding the area of a square with side lengths of 9 are:
- Area=9×9
- Area=9²
Both of these formulas calculate the area of the square by multiplying the length of one side by itself. For example, using the first formula, the area of the square would be 9 multiplied by 9, which equals 81.
