We see : 1000⁹⁹⁹ < 1000¹⁰⁰⁰

1000⁹⁹⁹ = 1000 . 1000 . ... . 1000 ( with 999 factor 1000 )

              = 1000...000 ( with 3 . 999 = 2997 digits 0 )

1000¹⁰⁰⁰ = 1000 . 1000 . ... . 1000 ( with 1000 factor 1000 )

                = 1000...000 ( with 3 . 1000 = 3000 digits 0 )

Infer : The first three digits on the left are 100
 

Because within case only 3411254357 is shared by 7

Should D = 5

A = 106

The rectangular area :

 11 * 13 = 143 ( cm² )

Perimeter retangular :

 ( 11 + 13 ) * 2 = 48 ( cm )

She has :

 10000 : 40 = 250 ( 40 dollars - bills )
