Answer :

Given: a photograph is 5 inches wide and 7 inches tall.

He wants to enlarge the photo to fit in a frame that is 32 inches tall.

So, the length and the width will be scaled proportionally

So, the scale factor = r= new length over the lod length

[tex]r=\frac{32}{7}[/tex]

It must be the same ratio: new width to old width

Let the new wide = x

so,

[tex]\frac{x}{5}=\frac{32}{7}[/tex]

solve for x:

[tex]x=\frac{32}{7}\cdot5=\frac{160}{7}=22\frac{6}{7}in[/tex]

So, the answer will be: the new width = 22 6/7 inches
