Take five (Posted on 2011-05-22) Difficulty: 4 of 5
A triangle is Heronian if all its sides and its area are integers.
Any such rational triangle can be scaled up to a corresponding triangle with integer sides and area, and often the term Heronian triangle is used to refer to the latter.
There are only 5 Heronian triangles (with all sides being integers) whose perimeters numerically are equal to their areas.

You are requested to find all of them.
