To measure the perimeter of a triangle, the lengths of sides AB, BC and CA are measured using a caliper with a resolution of 0.05 mm. Performing a single measurement for AB, BC and CA, the values AB= 50.20 mm are read; BC= 55.15 mm and CA= 40.65 mm. Determine the perimeter (P) of the triangle with its uncertainty (uP) and express the result in m. a) P±uP= (0.146000 ± 0.000050) m b) P±uP= (146,000 ± 0.050)x10-2 m c) P±uP= (146.00 ± 0.05)x10-3 m d) P±uP= (0.146 ± 0.050) m e) P±uP= (146.0 ± 0.05) m
