Answer:
3 m²
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
where b is the base of the triangle, and h is the height perpendicular to the base.
Application
Any side of the triangle can be chosen as the base. When a base angle is obtuse, as here, the perpendicular to the base intersects the base line outside the triangle. The formula still applies.
A = 1/2(3 m)(2 m) = 3 m²
The area of the given obtuse triangle is 3 square meters.
