1. Area of Parallelograms and Trapezoids
By “cutting” the pink triangular piece off of the parallelogram, you can see how it reattaches and shows a length x width solution in the rectangle.
Therefore the area of a parallelogram is base x height.

3. Find the area. Use A = bh 9 meters 3 feet 18.5 meters 2 ½ feet 10 cm
