  2. THEOREM 11-2 THEOREM 11-2 The area of a parallelogram equals the product of a base and the height to that base. A = bh !!!!!This side is not the height!!!! h h b b

  3. THEOREM 11-2 Find the area of the figure. 24√3 un² 60° 2 10

  4. THEOREM 11-2 Find the area of the figure. 27√2 un² 9 6 45°

  5. THEOREM 11-3 THEOREM 11-3 The area of a triangle equals half the product of a base and the height to that base. A = ½ bh h b

  6. THEOREM 11-3 Find the area of the figure. 276 mm² 12 mm 46 mm

  7. THEOREM 11-4 THEOREM 11-4 The area of a rhombus equals half the product of its diagonals. A = ½ d1 d2

  8. In rhombus ABCD, AC = 20 and BD = 15. The area can be found in more than one way. A = 150 un² A B 12 D C
