Multiply n by 2 i.e. \(n \times 2 \implies 2n\) Now add 1 to what we have got : \(2n + 1\) So, your expression is : \(2n+1\) And lastly I know about sketching the area model, I have not studied that, Sorry..

\[x\times2[\text{cm}]+y\times2[\text{in}]\] \[=x\times2[\text{cm}]+y\times2[\text{in}]\times\frac{2.45[\text{cm}]}{[\text{in}]}\]
