Linear measurements Problems 1) A line is measured with a tape of 20 m. The line is found to be 200 meters. The tape is then calibrated and found that its length is 19.9m. Find the correct length of the measured line? 2) A line is measured with a tape of 30 m. The line is found to be 250 meters. The tape is then calibrated and found that its length is 29.95m. Find the correct length of the measured line? 3) The area of a piece of land is measured with a tape of 50 m and found to be 8000 m2. The tape is then calibrated and found that its length is 50.90m. Find the actual area of the land? 4) The area of a piece of land is measured with a tape of 30 m and found to be 5000 m2. The tape is then calibrated and found that its length is 30.95m. Find the actual area of the land? 5) A line is measured with a tape of 20 m on a ground with 1:300 slope. The line is found to be 200 meters. The tape is then calibrated and found that its length is 19.9m. Find the correct length of the measured line? 6) A line is measured with a tape of 30 m on a ground with 1:100 slope. The line is found to be 400 meters. The tape is then calibrated and found that its length is 29.9m. Find the correct length of the measured line? Horizontal Reference: Plane Surveying I.
