Area of a Trapezoid

What name do we use to label the 2 sides that are parallel?

What properties do ALL trapezoids have?

Which two measurements can be used as the base 1 and base 2 for this trapezoid?

What is the height of this trapezoid?

What is the area of this trapezoid?

What name do we use to label the distance between the two bases?

Fill in the area formula for the green trapezoid.

$$A=\frac{1}{2}\cdot h\cdot\left(b_1+b_2\right)$$  

Shown is the correct formula for the green trapezoid. Which shows the next correct step?
$$A=\frac{1}{2}\cdot6\cdot\left(5+9\right)$$  

Shown is the correct next step in calculating the area. So what should the area be?

$$A=\frac{1}{2}\cdot6\cdot14$$  

Our answer was missing units! What should the area units be? (There are TWO correct answers!)

Fill in the area formula for the red trapezoid.

$$A=\frac{1}{2}\cdot h\cdot\left(b_1+b_2\right)$$  

Shown is the correct formula. What's next?

$$A=\frac{1}{2}\cdot5\cdot\left(4+8\right)$$  

Shown is the correct next step. What is the area of the red trapezoid?

$$A=\frac{1}{2}\cdot5\cdot12$$
