Area for any triangle is 1/2 base x height.
If you don't know the height (must be perpendicular to the base) then there are trig formulas depending on what is known.
Heron's formula is based on knowing the 3 sides (works for any triangle).
Step 1 find the semiperimeter, s. s = (a+b+c)/2
Step 2 find the area. A = sq root [s(s-a)(s-b)(s-c)]
If you only know 2 sides and an angle there are other formulas as well.

How do you calculate area of obtuse triangle?
Area = 0.5*base*altitude
Is it true that a obtuse triangle has a greater area than any acute triangle?
Not at all.
What is a triangle with an obtuse angle?
obtuse triangle
A triangle with 1 obtuse angle?
A triangle with 1 obtuse angle is called an obtuse triangle.
Does every triangle have at least one obtuse angle?
-- No right triangle, acute triangle, or equilateral triangle has an obtuse angle in it. -- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it .
