2. Lesson 9-1: Area of 2-D Shapes 2 s s A = s² 6 6 A = 6² = 36 sq. units L W A = LW 12 5 A = 12 x 5 = 60 sq. units Example: Area of Rectangle: A = LW Area of Square: A = s²

3. Lesson 7-2: The Pythagorean Theorem 3 A B C Given any right triangle, A 2 + B 2 = C 2

4. Lesson 7-2: The Pythagorean Theorem 4 A B C In the following figure if A = 3 and B = 4, Find C. A 2 + B 2 = C 2 3 2 + 4 2 = C 2 9 + 16 = C 2 5 = C
