# Ant problem!

**Geometry**Level pending

An ant, located in a square field, is \(13\text{ m}\) from one of the corner posts of the field, \(17\text{ m}\) from the corner post diagonally opposite to the first one, and \(20 \text{ m}\) from a third corner post. Assuming the land is flat, find the area of the field (in \(\text{m}^2\)).
