To find the flower border area we first find the area of the bif rectangle and substract the sitting area. With this idea in mind we have:


A=11(3x+6)-5(3x)

Now we do the operations given:


\begin{gathered} A=33x+66-15x \\ A=18x+66 \\ A=6(3x+11) \end{gathered}

Therefore the area of the flower border is 6(3x+11)
