we know that
The length of the row of quarters is equal to multiply the diameter of the quarter by the number of quarters in the row
so
For 4 quarters in the row, the length is equal to --> 
For 6 quarters in the row, the length is equal to --> 
For 12 quarters in the row, the length is equal to ->
