1. Geometry 1.6 Perimeter and Area

2. Perimeter Is the distance around a figure It is the sum of the lengths of the sides of the figure =side 1 +side 2 +side 3 +...+side n

3. Perimeter 9 5

4. Perimeter of a Rectangle l w P = l + w + l + w P= 2l + 2w

5. Area The area of a figure is the number of square units needed to cover its surface HUH?

6. Area 5 4

7. 5 4 The area of a Rectangle is found by multiplying the length and the width A = lw = l x w

8. Area of a parallelogram The area of a Parallelogram is the product of the base and the height. A = bh = b x h

9. What’s a parallelogram Four sides Opposite sides are parallel

10. Area of a parallelogram b The base is easy to find, but where is the height? h

11. Area of a parallelogram 7 4 A = bh A = 7(4) A = 28

12. Area of a parallelogram b h b Now it’s just like a rectangle

13. Area of a parallelogram = bh Perimeter of a Rectangle = 2l + 2w Area of a Rectangle = lw
