Since the lengths of all three sides are given, apply the Heron's formula to get the area.

It is pure mechanical calculation.

ANSWER. 204 cm^2.

-------------------------

In the  Internet,  you can find many online calculators for the Heron' formula.

To save my brain,  I used one of them https://www.mathopenref.com/heronsformula.html

In addition to making calculations,  it explain the formula itself,  so  I  have nothing to add to it.


On the Heron's formula,  see my lessons
