1. PERIMETER & AREA

2. The distance around any closed figure

3. Any polygon- P = s + s + s...

4. P = s + s + s... 8 in 15 in P = 8 + 3 + 3 + 15 + 3 + 3 + 8 + 3 + 3 + + 3 + 3 P= 70 in 8 in 15 in 3 in

5. Rectangle P = 2l 2l + 2w

6. P = 2l 2l + 8 cm 5 cm P = 2 8 + 2 5 P = 16 + 2 5 P = 26 cm P = 16 + 10

7. P = 4s 7 cm P = 4 7 P = 28 cm

8. The number of square units needed to cover a surface.

9. Rectangle A = lwlw

10. A = lwlw 8 cm 5 cm A = 8 5 A = 40 cm ²

11. Square A = s²s² A = s s

12. A = s²s² 7 cm A = 7 7 A = 49 cm ² A = 7²7²
