In a drawing with a scale of 1/4 inch = 1 foot, what does a line measuring 2-1/2 inches represent?

10 feet

15 feet
20 feet

To determine what a line measuring 2-1/2 inches represents on a drawing with a scale of 1/4 inch = 1 foot, you first need to convert the measurement in inches to feet based on the given scale. The scale indicates that for every 1/4 inch on the drawing, it corresponds to 1 foot in reality. To find out how many feet are represented by 2-1/2 inches, you'll perform the following calculations: 1. Convert the measurement in inches to a fraction of the scale: - Since 1 foot corresponds to 1/4 inch, you can express the total inches in terms of the scale. The calculation is done by dividing the total inches (2-1/2 = 2.5 inches) by the scale (1/4 inch). 2. You can express this as: - 2.5 inches / (1/4 inch per foot) = 2.5 * 4 = 10 feet. Thus, a line measuring 2-1/2 inches on that particular drawing represents 10 feet in reality. This calculation method allows you to accurately use the scale to interpret measurements in architectural drawings or carpentry plans. The indicated
