The area of the enlarged photo is 36 times as large as the area of the original.
Explanation
Noah enlarged a photograph by a scale factor of 6.
The rule we will use here is......
"If the side lengths of any shape are all enlarged by a scale factor of [tex]k[/tex], then the area will be enlarged by a scale factor of [tex]k^2[/tex]"
So, here the area of the photograph will be enlarged by a scale factor of [tex](6)^2 = 36[/tex]
