Given that:

Two Given polygons are similar :

Ratio of corresponding sides =. 1/6

p = 120/6

p = 20 yards

What geographical information was used in alloying the first three digits of social security numbers to the state
Gala2k [10]
Since 1973, social security numbers have been issued by our central office. The first three (3) digits of a person's social security number are determined by the ZIP Code of the mailing address shown on the application for a social security number. Prior to 1973, social security numbers were assigned by our field offices. The number merely established that his/her card was issued by one of our offices in that State.
