calculate the approximate area of the composite shape shown

Area =1/2

Step-by-step explanation:

the area of a triangle with a known base,(b) and height,(h)where h is perpendicular to the base and terminated by the vertex opposite the base,is represented by the following area: A=1/2.b.h

The area of any triangle with 2 known side lengths, a and b and an angle opposite the unknown side, c, is represented by the following formula: A=1/2.ab.sin (c)

Hero's formula defines the area of any triangle when given the lengths of all three sides, a, b, and c and the semiprimeter, s, which is half the primeter.
