You need a "conversion factor." If the real-life room is 10.5 feet wide, and the width of the scale model is 3.5 feet, use this info to come up with a scale factor.

i figured it out its 14 right?

Hint: 10.5 feet in real life corresponds to 3.5 feet in the model. You'll need to use this info to calculate the length of the model, given that the real life length is 12 feet/ Please show me how you figured it out, and then I'll give you feedback.

okay um 3.5 goes into 10.5, 3 times

so that means i had to divide 12 by 3 to get the length of the model, i got 4, and multiplied that by 3.5, to get 14

Is a scale model usually larger or smaller than the original (real life object)?

smaller

right. but according to your calculations, the 12 foot length in real life has become 14 feet in the model. Could that be right?

I can think of at least 2 ways in which to solve this problem. Let's set up ratios: width ;length model 3.5 feet ?? actual room 10.5 ft 12 ft
mathmale
  • mathmale
Cross multiply: (3.5 ft)(12 ft) = ??

the length is 4
