Question

The diagram represents a flower border that is 3ft wide surrounding a rectangular sitting area. Write an expression in factored format that represents the area of the flower border.

Answer 1

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)
