Awall that is 12 feet high on the building is 36 centimeters high on the model. find the height on the model of a door that is 9 feet high on the building.
i already solved this one. the answer is 27. im having trouble with part b.
(b) find the number of centimeters on the model for a window that is 3 feet wide.

9 centimeters

Step-by-step explanation:

Hi, to answer this question we have to apply the same ratio applied to find the height in centimeters of the door.

12ft/36cm = 9ft/x cm

12/36= 9/x

x = 9/ (12/36)

x =27cm

Using the value of the window's wide instead of the door's height.

12/36 = 3/x

x = 3 / (12/36)

x = 9cm

Feel free to ask for more if needed or if you did not understand something.

11 feet 6 inches and 8 feet 6 inches

the correct answer is d

hope this
