No problem at all!
I am here for your help.


The concept is: as the shape is minimized or enlarged, the sides will be proportional and the angles do not change (remain the same for the model and the original ones)

So, is it gonna be like this  1/4 x 54/1?

What I really actually have to do in here to solve this problem that I am having hard time to find and how to do it?

faman39 · Answer

You say I am confused everywhere in this question

"She built a scale model of the dollhouse with a scale ratio of 1:4"
That means the model sides will be 4 times the original corresponding ones!
and NO CHANGE IN ANGLES' MEASURES!
