I'm not sure why this is being marked as wrong. The answer to the next question was 16 so I know its correct. Im thinking there might be another way to write it?​

The total area is 376 square feet. The rectangle portion has an area of 120 square feet. That leaves 376-120 = 256 square feet for the square portion.

So we can say the following:


\text{x}^2 = 376 - 120\\\\\text{x}^2 = 256\\\\\text{x} = √(256)\\\\\text{x} = 16\\\\

Or a slight variation is this


\text{x}^2 = 376 - 120\\\\\text{x} = √(376 - 120)\\\\\text{x} = √(256)\\\\\text{x} = 16\\\\

The side length of the square portion is 16 feet.
