If a building is 30 feet long and drawn to a scale of 1/2 inch equals 1 foot, how long is it drawn on paper?

If a building is 30 feet long and drawn to a scale of 1/2 inch equals 1 foot, how long is it drawn on paper?

• A. 10 inches
• B. 12 inches
• C. 15 inches
• D. 20 inches

Answer: (C)

To determine how long the building will be drawn on paper at the given scale of 1/2 inch equals 1 foot, we first need to understand what this scale means. The scale indicates that every 1/2 inch on the drawing represents 1 foot in real life. Given that the building is 30 feet long, we can calculate the length on paper by following these steps: 1. **Determine the number of feet the scale represents**: Since 1/2 inch equals 1 foot, we need to find how many 1/2 inch segments are in 30 feet. 2. **Calculate the total number of 1/2 inch increments in 30 feet**: Since 1 foot consists of 2 increments of 1/2 inch (because 1 foot = 2 * 1/2 inch), we can multiply 30 feet by 2 to get the total number of increments: \[ 30 \text{ feet} \times 2 = 60 \text{ increments of 1/2 inch} \] 3. **Convert the increments back to inches**: Each increment is represented by 1/2 inch, so to find the total length in

To determine how long the building will be drawn on paper at the given scale of 1/2 inch equals 1 foot, we first need to understand what this scale means. The scale indicates that every 1/2 inch on the drawing represents 1 foot in real life.

Given that the building is 30 feet long, we can calculate the length on paper by following these steps:

1. Determine the number of feet the scale represents: Since 1/2 inch equals 1 foot, we need to find how many 1/2 inch segments are in 30 feet.

2. Calculate the total number of 1/2 inch increments in 30 feet: Since 1 foot consists of 2 increments of 1/2 inch (because 1 foot = 2 * 1/2 inch), we can multiply 30 feet by 2 to get the total number of increments:

[

30 \text{ feet} \times 2 = 60 \text{ increments of 1/2 inch}

3. Convert the increments back to inches: Each increment is represented by 1/2 inch, so to find the total length in
