You find an old scale drawing of your home,but the scale has faded and you cannot read it. How can you find the scale of the drawing?
Measure one actual room, and then measure the same room on the drawing.
To find the scale of the faded drawing, you can follow these steps:
1. Use a ruler: Measure a known distance on the drawing that corresponds to a known distance in your actual home. For example, measure the length of a wall on the drawing using a ruler.
2. Measure the same distance in your actual home: Use the same ruler to measure the length of the corresponding wall in your home.
3. Calculate the scale factor: Divide the measured length on the drawing by the measured length in your actual home. For instance, if the measured length on the drawing is 10 centimeters and the measured length in your home is 5 meters, the scale factor would be 10 cm / 5 m = 1/50.
4. Convert the scale factor: Convert the scale factor into a representative fraction or ratio. In this example, the scale factor 1/50 can be converted to 1:50 or 1 unit on the drawing represents 50 units in reality.
By following these steps, you should be able to determine the scale of the faded drawing.
To find the scale of the faded drawing, you can use the dimensions of any known feature in your home and compare them to the dimensions on the drawing. Follow these steps:
1. Identify a known feature: Choose an object or feature in your home that you can easily measure. It could be the length of a wall, the width of a door, or the height of a window. Make sure you measure it accurately.
2. Measure the feature: Use a measuring tape or any reliable measuring tool to measure the chosen feature in your home. Note down the measurement in feet, inches, or centimeters, depending on your preference.
3. Locate the same feature on the drawing: Look for the corresponding feature on the faded drawing. Find a matching wall, door, or window, and locate the associated dimension, which is usually represented as a straight line with a measurement.
4. Compare the measurements: Compare the measurement you obtained in step 2 with the dimension on the drawing. If the drawing's dimension is longer, divide the actual measurement by the drawing's measurement to calculate the scale. If the drawing's dimension is shorter, divide the drawing's measurement by the actual measurement.
For example, let's say the actual length of a wall in your home is 20 feet, while the dimension on the drawing appears to be 4 inches.
Divide the actual measurement (20 feet or 240 inches) by the drawing's measurement (4 inches):
240 inches ÷ 4 inches = 60.
This means that, based on this comparison, the scale of the drawing is 1 inch represents 60 inches (or 1:60 scale).
Repeat this process using other known features in your home to confirm the scale of the drawing. Keep in mind that if the drawing is not proportionally accurate, the scale may vary in different areas.
