4. The area of a rectangle is the product of its base and height.
A = bh

5. Area of a Parallelogram
The area of a parallelogram is the product of a base and the corresponding height. h b
A = bh

6. The base of a parallelogram is any of its sides.
The corresponding altitude is a segment perpendicular to the line containing the base drawn to the side opposite the base.
The height is the length of the altitude. h b h b

7. Find the area of the parallelogram.

9. Find the value of h in each parallelogram.

10. A diagonal divides any parallelogram into two congruent triangles.
