Answer:

begin mathsize 12px style Let space the space scale space be space straight k equals fraction numerator 1 space cm over denominator 10 space space straight m end fraction equals 1 over 1000
Scaled space area equals straight k squared cross times actual space area
space space space space space space space space space space space space space space space space space space space space space space space equals 1 over 10 to the power of 6 cross times 500 cross times 10 to the power of 4 space cm squared equals 5 space cm squared
Scaled space length equals 5 space cm
So space scaled space width equals fraction numerator scaled space area over denominator scaled space length end fraction equals 1 space cm end style
