Question

what is the expression?what is the overall area of the garden space?how can u find out the total area of walking spaces?

Answer 1

we have the following:

`p=2\cdot w+2\cdot l`

therefore, replacing:

`\begin{gathered} p=2\cdot(x+3+x)+2\cdot(x+3+x+3+x) \\ p=2\cdot(2x+3)+2\cdot(3x+6) \\ p=4x+6+6x+12 \\ p=10x+18 \end{gathered}`

the answer is, the perimeter is 10x + 8
