We have a rectangle with length L=x-8 and width W=x+11

Let's remember that the area of a rectangle is given by the following equation


A_R=L\cdot W

We replace these values


A_R=(x+11)(x-8)

We multiply and solve


\begin{gathered} A_R=x^2-8x+11x-88 \\ A_R=x^2+3x-88 \end{gathered}

The answer is option B
