Check the picture below.
so the composite is just 2 triangles, one rectangle and one parallelogram.
we know the height and base of the triangles and length and width of the rectangle.
now, the parallelogram, we can simply split in in two triangles and a rectangle, like you see the split in the middle, and that gives us two more triangles and one rectangle.
so, we can simply get the area of each of those figures and sum them up, and that's the area of the composite.
