About area of triangles, parallelograms and trapezoids

Each shape is drawn to scale with its base or bases labeled and the height shown as a dashed line with a right-angle mark, so students pick the height and ignore the slanted side. Triangles may lean, with the height inside the base, and every area is a whole number.

Choose one shape or a mix, and the units. The solved example shows the formula with the numbers put in, and the answer key writes every area.
