  3. Perimeter A square has 4 sides for the fence. 12 12+12+12+12=48 The perimeter is 48. 12 12 12

  4. Area • Area is the ENTIRE INSIDE of a shape • It is always measured in “squares” (sq. inch, sqft)

  5. AREA • Square units means“that” many squares fit inside that shape (if measured in feet…it’s feet…if meters…it’s meters. In this example the area is 4 square units…note 4 squares fit) 1 2 3 4
