This Visual Diagram helps to remember the formula very easily

It's a part of Heron Formula, right ? 😁

[EdwardNavu]

why do i smell heron's formula despite a lack of relevance?
must have something to do with the semiperimeter...

It is so unusual to see s as semiperimetr. S is usually the area, perimetr is P and semiperimetr is p..
