Reducing scale

I am sizing some landscaping and I measured everything for a 20 to 1 scale. I realized when I was done that it was at 30 to 1. How can I convert what I already have to 30 to 1. (Example, grass area is 22,871.6' at 20 to 1, how do you figure it out to be 30 to 1?

Correct answer:

k =  0.6667

Step-by-step explanation:

k=2030=230.6667 A=228716 B=k A=0.6667 228716=4574323=15247713152477.3333 k=0.6667=23
