Answer 1

`\text{The current size of 4 inches by 6 inches}`

If we want to enlarge the picture by a factor of 4.5, the perimeter will also increase by the factor of 4.

`\begin{gathered} \text{New dimension =}4.5\text{ (old dimension)} \\ \text{New dimension=4.5 (4 by 6)} \\ \text{New dimension=18 inches by 27 inches} \end{gathered}`

Hence, the correct option is Option A
