A high tech company uses a satellite to measure the size of features on the surface of the earth. They use this technology to measure a particular rectangular field and find it's length to be 444 ± 1.8 in meters and it's width to be 198 ± 1.63 in meters. They plan to report the perimeter (sum of two lengths and two widths) of the field as P± SP in units of yards. (1 meter = 1.094 yards) What is SP?

An astronomical unit (AU) is equal to the distance from Earth to the Sun, about 149.6 million km. A Parsec (pc) is the distance at which a length of 1 AU would subtend an angle θ of exactly 1-second of an arc. A light-year (Ly) is the distance that light, traveling through a vacuum with a speed of 3.0 x 108 m/s, would cover in 1 year (365 days). Express the Earth-Sun distance in: a) Parsec (pc) units. b) Light-year (Ly) units.
