Propositiones ad Acuendos Juvenes/Problems/29 - De Civitate Rotunda/Solution 2

Solution
The boundary of the town is $8000$ feet.

Take a quarter of $8000$, getting $2000$.

Again take a third of $8000$, getting $2666$.

Take the half of $2000$, which is $1000$, and the half of $2666$, which is $1333$.

Not the thirtieth part of $1333$ is $44$.

Likewise the twentieth part of $1000$ is $50$.

$50$ times $44$ is $2200$.

Then form $2200$ times $4$ whch is $8800$.

This is the total number of houses.
