Emily’s father built a doll house, to scale, based on their house. Emily’s room is 12 ft long and 10 ft wide. The same room in the dollhouse is 8.5 in. long. What is the approximate width of Emily’s room in the dollhouse?

7.0833 inches

Step-by-step explanation:

As Emily's room in the dollhouse has its dimensions as a scale of Emily's room, we can solve this problem using rule of three:

The room has 12 feet long, and its scaled room has 8.5 inches long, so if the room has 10 feet wide, the width of the scaled room is X:

12 feet -> 8.5 inches

10 feet -> X inches

12/10 = 8.5/X

X = 10 * 8.5 / 12

X = 7.0833 inches
