Question

What size(in inches) should they use for a scaled copy of Mona Lisa on notebook cover so that the picture is a big as it can possibly be but still fit on the paper? Note: there might be some extra space on one dimension

Answer 1

First, let's convert each dimension into inches:

`\begin{gathered} 2.5ft\rightarrow30in \\ 1.75ft\rightarrow21in \end{gathered}`

Now, we can calculate the lenght to width ratio:

`30\colon21\rightarrow10\colon7`

Now, we can use the dimensions of the cover and a rule of three to calculate our maximum width:

This way,

`x=(11\cdot7)/(10)\rightarrow x=7.7`

Therefore, we can conclude that the picture on the cover should measure 11" by 7.7"
