The acceptable measurement of the length of the piece of paper is 3.5 cm.
<h3>What is measuring accuracy of a ruler?</h3>
The measuring accuracy of ruler determines how precise or accurate the length of an object is measured.
The limit of accuracy of a ruler is indicated by how "precisely" you can read the length on that ruler's scale—that is, how well you can estimate between the marks.
In a ruler the distance between the closest marks is 0.1 cm.
This implies that the measuring accuracy of meter rule is 0.1 cm.
The acceptable measurement of the length of the piece of paper is calculated as follows;
length = (3 cm + 4 cm)/2 = 3.5 cm
Thus, the acceptable measurement of the length of the piece of paper is 3.5 cm.
