Question

an architect is presenting a scale model of a building she's designed to the planning committee of college the scale of the model is 1 in = 18 ft if the tallest wall in the model is 12 in high how tall will the actual building be?

Answer 1

The tall of the actual building will be 216 feet

Step-by-step explanation:

An architect is presenting a scale model of a building she's designed

to the planning committee of college

1. The scale of the model is 1 inch = 18 feet

2. The tallest wall in the model is 12 inches

3. We need to know how tall the actual building will be

Let us used the ratio method

∵ The scale of the model is 1 inch represents 18 feet

∵ The tallest wall in the model is 12 inch

→  Model(in)    :    Actual(ft)

→  1                  :    18

→  12                :    h

- By using cross multiplication

∴ 1 × h = 12 × 18

∴ h = 216 feet

∴ The actual height is 216 feet

The tall of the actual building will be 216 feet

Answer 2

Answer:

216

Step-by-step explanation:

1. Write the scale ratio:

1.in.

18 ft.

2. Write the ratio of the height of the wall in the model to the height of the actual wall

12in.

h ft.

3. write a proportion that equates the two ratios:

1 =12

18 =h

4. cross multiply:

h=12*18

5. multiply to find h

h=216

The actual building will be 216 feet tall
