  1. Lesson 11.2 Area of Parallelograms and Triangles

  2. Theorem 100 The area of a parallelogram is equal to the product of the base and the height. A = bh where “b” is the length of the base and “h” is the height

  3. Theorem 101 The area of a triangle is equal to one half the product of the base and the height (or altitude) for that base. A = ½(b x h) where b is the length of the base and h is the altitude

  4. Problems 12 in. 1. Find the area of the parallelogram. 6 in.

  5. Problems 2. Area = 60 Find the base of the triangle. 15 |----------- b -----------|

  6. Problems 3. Find the area of the triangle. 24mm 30*

  7. Problems 4. Find the area of parallelogram 6 cm 60° | --- 14cm --- |
