so in the first scale suing the rule of 3 simple you can calcule that 
when 1 in mean 4 ft 
          5 in mean x ft so cross multiplie and calcule the x value

x = 5*4/1 = 20 ft

using this way to the new scale drawing of 1 to 6

when 1 in mean 6 ft 
so 5 in mean x ft

x = 5*6/1 = ? ft

hope this is an understandably way so in this way you can calcule the width too

hope helped
