Question

An architect created a scale model of a building that was to be built.

Answer 1

Answer:

105 ft

Step-by-step explanation:

In this case, the first thing is to calculate the scale, therefore, we must divide the real measurement by the model measurement, like this:

45 ft / 3 ft = 15

Which means that the scale is 15.

Now, to calculate the height, we must multiply the height of the model by the scale, that is:

7 ft * 15 = 105 ft

which means that the height of the building is 105 ft
