Question

Noah enlarged a photograph by a scale factor of 6. The area of the enlarged photo is how many times as large as the area of the original?

Answer 1

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 $k$, then the area will be enlarged by a scale factor of  $k^2$"

So, here the area of the photograph will be enlarged by a scale factor of  $(6)^2 = 36$
