You say that 3 acres of land is required for one of these schooners. I want to ask question in order to understand it better. Question 1-) If 3 acres of land are required for 1 schooner, this means 6 acres of land for 2 schooners and 9 acres of land for 3 schooners? Or, as the number of schooners increases, will the amount of land for each schooner decrease with formulas such as common uses? Question 2-) Does 1 acre and 1 decare mean "the same amount of land"? In other words, do decare and acre mean the same amount of land?
