Opening Exercise

Name each shape.

A rectangle is considered a parallelogram, but is commonly called a rectangle because it is a more specific name.

Discussion

Cut out a parallelogram and how can we change the parallelogram into a rectangle.

Lesson Summary

The formula to calculate the area of a parallelogram is A = bh, where b represents the base and h represents the height of the parallelogram.

The height of a parallelogram is the line segment perpendicular to the base. The height is drawn from a vertex that is opposite the base.

Lesson 1 Exercises

- Find the area of each parallelogram below. Each figure is not drawn to scale.
- Draw and label the height of each parallelogram. Use the correct mathematical tool to measure (in inches) the base and height, and calculate the area of each parallelogram.
- If the area of a parallelogram is 35/42 cm
^{2}and the height is 1/7 cm, cm, write an equation that relates the height, base, and area of the parallelogram. Solve the equation.

Explore why the formula A = bh is used for rectangles and parallelograms.
