Final answer:
To find the actual height of a building on a scale drawing, set up a proportion using the given scale. In this case, the actual height is 405 feet.
Step-by-step explanation:
To find the actual height of the building, we need to use the given scale. The given scale is 1 inch = 60 feet, which means 1 inch on the scale drawing represents 60 feet in reality. The height of the building on the scale drawing is 6.75 inches, so we can set up a proportion to find the actual height:
1 inch / 60 feet = 6.75 inches / x feet
Cross multiplying: 1 * x = 6.75 * 60
Simplifying: x = 405 feet
Therefore, the actual height of the building is 405 feet.
