Rachel designs a square tablecloth. Each side of the tablecloth measures 6 feet. What is the tablecloth's area?

To find the area of a square, you multiply the length of one side by itself.

Therefore, to find the area of the tablecloth, you multiply 6 feet by 6 feet:

6 feet x 6 feet = 36 square feet

So, the tablecloth's area is 36 square feet.
