36x2(for the total amount of yarn for the width) would be 72. 112-72=40. Since it is a rectangle and the width should both be the same size, the length should be 20 inches. (20+20+36+36=112, so 20 inches is the correct answer.
It can be noted that the percentage error made by Allison will be 1.6%
<h3>How to solve the percentage</h3>
From the information given, Allison measured a line to be 19.4 inches long and the actual length of the line is 19.1.
Therefore, the percentage error will be:
= (19.4 - 19.1)/19.1 × 100
= 0.3/19.1 × 100
= 1.6%
In conclusion, the correct option is 1.6%.
