Answer:
16x feet
Explanation:
A scale of 1/4" = 4' means that every 1/4 inch on the drawing or map represents 4 feet in the actual measurement. To find the actual length of a line on the drawing or map, you need to multiply the length of the line in inches on the drawing by the denominator of the scale, and then divide by the numerator of the scale.
The formula is:
Actual length = (length on the drawing or map x scale denominator) / scale numerator.
In this case, the length on the drawing or map is x inches, and the scale is 1/4" = 4'.
So the actual length is: (x inches x 4') / 1/4" = 16x feet
Therefore, the actual length of the line on the drawing or map is 16x feet.
