This stamp has been stuck on centimeter-squared paper. Take each square to have a side of 1 cm.

**Perimeter is the distance around the edge of a figure.**

If an ant walks around the sides of the stamp it would need to walk 4 + 3 + 4 + 3 = 14 cm.

So, the perimeter of the stamp is 14 cm.

Perimeter = 2 × (l + b)

**Area is the amount of surface a figure covers.**

Glue would have been applied to 12 squares in order to stick the stamp.

We can say that the stamp covers an area of 12 square centimeters or 12 sq. cm.
