Find the missing dimension. use the scale factor 1: 8. set up a proportion model length: 6cm actual length: ?

1:8, so for every cm drawn, it is 8 cm in real life.
because the model length is 6cm, you multiply 8 by 6:
8*6 = 48
So the actual length is 48 cm

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
