A square tablecloth has a perimeter of 12 feet. what is the area of the tablecloth?

Even though, this should not be in the english category, the answer is 144 ft squared.

Perimeter = 2length + 2width

Since this is a square, we know that length and width are the same so the equation becomes:

Perimeter = 4 length

length = perimeter/4

length = 12ft / 4

length = 3 ft

Now we use the side length to find area.

Area = length * width

Since they are the same in a square:

Area = length²

Area = (3 ft) ²

Area = 9 ft²

Therefore, the area is 9 square feet.
