This paper contains interesting and elegant proof of the Heron's Formula obtained by high school student Miles Edwards, published in American Mathematics Monthly, Vol. 114, No. 10, 2007, p. 937 . The proof is interesting for its usage of complex numbers. In this paper we wanted to emphasize that this proof illustrates that sometimes unusual approach to standard problems can produce interesting and skillful, precise mathematical result.
