Answer: all sides of the apartment would be cut in half.
Step-by-step explanation: so because we are going from 8 ft to 4ft, the sides would be cut in half as shown on the image attached. for example, instead of the bottom being 4 tiles long, it would now be 2 tiles long. another example would be that instead of one of the sides being 3 tiles long, it would now be 1.5 tiles long. you would basically divide the length of each side by two! hope this helps :)
