Part 1: Propagation and Basic Equations

1. Problem 1:Four lengths of fence are measured and found to be 4.57 m, 6.24 m, 4.24 m, and 5.78 m. Each measurement has an uncertainty of 0.10 m. FindP_m, the perimeter and uncertainty.
   1. On a separate piece of paper, write the equation for perimeter:P=l₁+l₂+w₁+w₂. Find the value ofPand show your work. Figure 9 is an example of how the calculations should be written.
