Question

A wall 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.

Sorry if it's confusing that's just how the assignment asked it.

Answer 1

Answer: 27 centimenters high

Explanation:

36/12 = 3

9*3=27

The door is 27 centimeters high

Answer 2

We have this proportion....

36 / 12 = x / 9 where x is the model door height

Cross-multiply

36*9 = 12 * x

324 = 12 *x divide both sides by 12

27 = x and that's the model height in centimeters
