The formula for the area of a rectangle is A= l x w

For the AREA questions below, write your numerical answers followed by the words square units.

The formula for the perimeter of a rectangle is P= l + l + w + w or P= 2 (l + w)

For the PERIMETER questions below, write your numerical answers followed by the words units.

* ALL WORK for today's lesson below should be done on the formative. The first six questions don't require any work.
