Question

The dimensions of rectangles A and B shown6ft nft3ft

Answer 1

The area of the given rectangle is given by

`\begin{gathered} A=\text{wide}* length \\ A=3*(6+n) \end{gathered}`

By distributing the number 3, we get

`\begin{gathered} A=3*6+3* n \\ A=18+3n \end{gathered}`

By comparing our results, we can see that option 1, option 3 and option 4 are true. that is,

`\begin{gathered} A=18+3n \\ A=3*(6+n) \\ A=3* n+3*6 \end{gathered}`

the rest of them are false
