1. Area of a Trapezoid

2. What did you discover? We can find the area of a trapezoid by dividing it into other figures. Let’s look at the 3 ways to find the area of this trapezoid.

3. Make 2 triangles and a rectangle Area of Trapezoid = area of triangle A + area of rectangle B + area of triangle C

4. Make 1 triangle and a parallelogram Area of trapezoid = area of parallelogram D + area of triangle E

5. Make 2 triangles Area of trapezoid = area of triangle F + area of triangle GArea of trapezoid = area of triangle F + area of triangle G

6. What formulas do we need… Area of a Rectangle: Area of a Triangle: Area of a Parallelogram:

7. And remember to follow the steps for using formulas. Step 1: write the formula Step 2: substitute in the known values Step 3: solve with proper units

8. Area of Trapezoid = area of triangle A + area of rectangle B + area of triangle C
