Answer:
42.5 units²
Explanation:
Total height of rectangle = 3.5 + 2 = 5.5 units
Total area (without triangles removed) = 5.5 x 9.0 = 49.5 units²
The measurements and area of the triangles removed are equal to those on the diagram, so calculate the area of the triangles and subtract them from the total area.
Left: (0.5)(2)(2) = 2 units²
Right: (0.5)(5)(2) = 5 units²
Area: 49.5 - 2 - 5 = 42.5 units²
