Answer:
The precision on this measurement is 0.1 cm
Explanation:
The precision on every measuring device depends on the graduation of the measuring device, and this precision can be obtained by the smallest division on the device.
72 centimeters length can be measured with a meter rule. The smallest division on a meter rule is 1 mm = 0.1 cm.
Then, a 72 centimeters length can be measured as 72 cm +/- 0.1 cm with a meter rule.
Therefore, the precision on this measurement is 0.1 cm
