Answer:
when we know the base and height it is easy.
It is simply half of b times h
Area = 1/2 bh
When we know two sides and the included angle (SAS), there is another formula (in fact three equivalent formulas) we can use.
Depending on which sides and angles we know, the formula can be written in three ways:
Area = 1/2 ab sin C
Area = 1/2 bc sin A
Area = 1/2 ca sin B
They are really the same formula, just with the sides and angle changed.
