Workbook 3A Lesson 3.2: Deductive Reasoning 3. Use the diagrams and information provided to complete the proof that the area of a trapezoid is h(Ll + L2) 2 . Diagrams and Information Explanation Hint: The sum of the areas of the smaller pieces will equal the area of the trapezoid. Your explanation will need to use the fact that L2 = L1 + a + b as shown in the second diagram. 20 ADLC Mathematics 20-2 Lesson 3.2: Deductive Reasoning Workbook 3A @ 4.
