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


(l_1)/(l_2)=(w_1)/(w_2)=k

Thus, we have the dimension of the other frame to be:


2\text{ feet wide and 4 feet long}

The correct option is C
