I need help

9 times 9 is 81

To find out how many 1-inch square tiles Sarah needs to line the square tray, we need to determine the total number of tiles that can fit in the area of the tray.

The area of a square is calculated by multiplying the length of one side by itself. In this case, since the side length of the tray is 9 inches, the total area would be 9 inches multiplied by 9 inches, which is 81 square inches.

Now, to find out how many 1-inch square tiles can fit into this area, we can divide the total area (81 square inches) by the area of each individual tile (1 square inch).

81 square inches รท 1 square inch = 81 tiles

Therefore, Sarah needs 81 tiles to line the square tray.
