  1. How do you find the area of a trapezoid?

  2. In this lesson you will learn how to find the area of a trapezoid by composing a parallelogram.

  3. You find the area of a rectangle by multiplying length times width. width length

  4. You find the area of a parallelogram by multiplying the base by height. height base

  5. When decomposing a trapezoid, it is often forgotten to find half the area of the shape you’ve created.

  6. Let’s find the area of a trapezoid. 21 x 5 5 units 52.5 units ¤ 2 105 units¤ 21 units

  7. Let’s find the area of an isosceles trapezoid. 16 x 3 3 units 24 units ¤ 2 48 units¤ 16 units

  8. In this lesson you have learned how to find the area of trapezoids by composing a parallelogram.

  9. Find the area of the trapezoid.

  10. Draw a trapezoid on a piece of grid paper. Then, draw a congruent trapezoid. Connect the two trapezoids to form a parallelogram. Find the area of the parallelogram. Using the area of the parallelogram, find the area of each trapezoid.

  11. Using pattern blocks, put together shapes to create a trapezoid. Trace the trapezoid onto grid paper and then find the area using the strategies you’ve watched in this video.

  12. 2. Find the area. 1. Find the area.
