A wall in the shape of a square

What are the dimensions of this wall?

To find out how many square feet of the wall Erica painted, we need to determine the area of the square.

Let's assume that the total area of the wall is x square feet.

We know that Erica painted all but 6 square feet of the wall, which means she painted x - 6 square feet.

Since the shape of the painted area is a square, the area of the square is equal to the previously calculated quantity x - 6 square feet.

Therefore, Erica painted x - 6 square feet of the wall.
