Question 14 (3 points

When describing the scale of a drawing, an architect describes it as 15:20. If the
length of a wall on the drawing was 10 inches, how long would that wall be in the
actual building?
20 inches
200 feet
20 feet
20 centimeters

Answer 1

When the scale of a drawing is described as 15:20, the length of a wall in the actual building can be found by setting up a proportion.

Step-by-step explanation:

When the scale of a drawing is described as 15:20, it means that for every 15 units on the drawing, there are 20 units in the actual building. To find the length of the wall in the actual building, we can set up a proportion:

15 units (drawing) / 20 units (actual) = 10 inches (drawing) / x inches (actual)

By solving this proportion, we find that the length of the wall in the actual building is 20 inches. Therefore, the correct answer is 20 inches.
