You want to calculate the area of your dorm room which is in a rectangular shape. You measure the length and the width of the room as L = 5.8 +- 0.1 m , W = 3.5 +- 0.1 m. What is the absolute error in the area in m2 units? You purchased 5.8 kg of apples from Wollaston. You noticed that they used a spring scale with the smallest division of 8.6 g to weigh them. What is the relative error in this weight measurement as a percentage?
[For example, if you find it to be 1.2% you should enter 1.2 in the answer box.]
