If a U.S. scaled drawing of 1/8 inch = 1 foot measures 4.25 inches, what is the actual length?

To find the actual length represented by a scaled drawing where 1/8 inch equals 1 foot and the measurement is 4.25 inches, first convert the scaled drawing measurement into feet using the scale provided.

The scale of 1/8 inch to 1 foot indicates that for every 1/8 inch of the drawing, the actual length is 1 foot. To determine how many 1/8 inch segments fit into 4.25 inches, divide 4.25 by 1/8. This is performed by converting the division into a multiplication by the reciprocal:

4.25 ÷ (1/8) = 4.25 × 8 = 34.

This calculation shows that there are 34 segments of 1/8 inch in 4.25 inches. Since each segment corresponds to 1 foot, the actual length represented by the measurement is 34 feet.

The correct choice reflects this simple principle of scaling in relation to the specified measurements.
