  1. Perimeter of Geometric Figures How can we determine the perimeter of figures?

  2. Perimeter • distance around the outside of a shape • count the outside of the tiles around the shape

  3. How to Count: 3 units 4 units 4 units 4 units 16 units 4 units 15 units 15 units 4 units 8 units 3 units 36 units 8 units 20 units

  4. What’s the perimeter? 28 units 30 units 40 units 10 units

  5. What’s the perimeter? 12 units 10 units 10 units 12 units Length + Length+ Width + Width 12 + 12 +10 + 10= 44 units

  6. What’s the perimeter? 5 units 4 units Length + Length+ Width + Width 5 + 5 + 4 + 4= 18 units

  7. Determine the perimeter. 3 units 6 units Length + Length+ Width + Width 6 + 6 + 3 + 3= 18 units

  8. Challenge! 60 units 14 units 8 units 8 units 5 units 5 units 8 units 8 units 4 units

  9. Find the perimeter. 10 in. 8 in. 8 in. 10 in. 36 in.

  10. Calculate the perimeter. 9 cm. 2 cm. 2 cm. 9 cm. 22 cm.

  11. Determine the perimeter. 5 ft. Side + Side + Side + Side 5 + 5 + 5 + 5 = 20 ft.

  12. Find the perimeter. 3 m. 3 m. 3 m. 3 m. 4 x Side 4 x 3 = 12 m.

  13. Calculate the perimeter. 4 yd. 8 yd. 8 yd. (2 x Length) + (2 x Width) ( 2 x 8) + (2 x 4) = 16 + 8 = 24 yd 4 yd.

  14. Find the perimeter. 2 mm. 4 x Side 4 x 2 = 8 mm.

  15. Calculate the perimeter. 4 in. 10 in. (2 x Length) + (2 x Width) (2 x 10) + (2 x 4) = 20 + 8 = 28 in.
