Answer
Bot
To find the length of a side of the tray, we can take the square root of the area:

√81 = 9

So the tray has sides that are each 9 inches long.

To find the perimeter of the tray, we can add up the length of all four sides:

Perimeter = 4 x length of one side
Perimeter = 4 x 9
Perimeter = 36

So the perimeter of the tray is 36 inches.
