Final answer:
On a drawing with a scale of 1/4 inch to 1 foot, one-quarter inch represents 1 foot of actual size.
Step-by-step explanation:
On a drawing where 1/4 inch represents 1 foot of actual size, one-quarter inch denotes c) 1 foot. This is a scale drawing problem where you use the provided scale to determine actual distances. For example, if a drawing has a scale of 1" = 10 ft, and the building on the drawing measures 10 inches by 14 inches, the actual dimensions would be 100 feet by 140 feet. Similarly, a line 4 inches long on the drawing would represent an actual line of 800 feet. When we talk about scale factors, if the dimension on the scale drawing is 4, and the scale factor is 1:4, you can calculate the actual dimension using the proportion 1:2=4:x.
