Scale Factor

Given two shapes, the second shape with dimensions proportional to the first shape with a scale factor of k.

The area of the scaled shape will be equal to the factor k squared.

We are given the areas of two similar shapes:

A1 = 64 square cm

A2 = 121 square cm

The scale factor of the areas is k squared, so:


k^2=(121)/(64)

Taking square root:


\begin{gathered} k=\sqrt{(121)/(64)} \\ k=(11)/(8) \end{gathered}

Answer: Last choice 11/8
