## Junius Moderatus Columella's Problem.

From the work "De re rustica".
95. Solution of Niphus

\[
\Delta=\sqrt{p(p-a)(p-b)(p-c)}=\sqrt{12 \cdot 6 \cdot 4 \cdot 2}=24
\]

It would have been simpler, of course, to take half the product of the legs.

Junius Moderatus Columella (1st century AD) in his treatise "On Agriculture," when discussing land surveying, indicates 9
land measures and solutions to nine geometric problems with numerical data.
