Answer to Question #156584 in Civil and Environmental Engineering for Tam

Question

A 50 m tape was used to layout a line. The length of the line is 120.23 m long. If the tape is 0.04 m too long, what is the laid out length of the line?

Answer 1

Tape measure with error = 50 meters

50 meters generate an error of 0.04meters

Required distance is 120.23 meters

Therefore if 50m generate 0.04m error what about the error per meter

0.04/50 = 0.0008 m

A distance of 120.23 will generate an error of

120.23 X 0.0008 = 0.096184 meters

Therefore the laid out length is

0.096 + 120.23 = 120.326m

The answer is 120.33 Meters
