You have measured a rectangular surface with sides of length 49.8 plus/minus 0.4cm and width of 48.2 plus/minus 0.8cm. What is the perimeter and area of this surface? Be explicit with your error calculations. I.e., state the formula for perimeter and area and the error calculations for each, then substitute the given values. (See below if you need help with the error.) Where (x-x) i = N-1 x, is the value of ith individual measurement (i = 1, 2, 3, ..., N) X is the average of all the measurements N is the number of measurements.
