## Recap

Perimeter is the distance around the outside of a shape.

Area measures the space inside a shape.  We measure area in meters squared which is written as m2

Example:

Perimeter: Add all the length and width measurements: 8cm + 4cm + 8cm + 4cm = 24cm

Or add one Length + one Width and multiply by 2: (8cm + 4cm) x 2 = 24cm

Area: Length x Width: 8cm x 4cm = 32cm2
