Solution:
Similar shapes are enlargements of each other using a scale factor.
Given that the two rectangular frames are similar, where one frame is 3 feet wide and 6 feet long.
This implies that
[tex]\frac{l_1}{l_2}=\frac{w_1}{w_2}=k[/tex]Thus, we have the dimension of the other frame to be:
[tex]2\text{ feet wide and 4 feet long}[/tex]The correct option is C
