What is the relationship between the length and wide of a rectangle and perimeter?



You can find the perimeter of a rectangle a few different ways.
1.  Add the length and the width, then multiply your answer by 2 or double it.
     20 m + 25 m = 45 m      45 m x 2 = 90 m
2. Double the length, double the width, then add.
   20m + 20 m = 40 m    25 m = 25 m = 50 m      40 m + 50 m = 90 m
3.  Add the length of each side.
     20 m + 20 m + 25 m + 25 m = 90 m

Whatever strategy you choose, the answer will always be the same. Perimeter is a linear measurement so the units are units of length such as mm, cm, dm, m, km.

Real life applications of perimeter include: trim, baseboards, frames and fences.

Social Studies
Today we talked about the people and natural resources in the Great Lakes-St Lawrence Lowlands. One natural resource is water. Do you remember how ships travel from Lake Erie to Lake Ontario? What is the problem? Use the diagrams to explain to a parent how locks work.





Soil is an important natural resource in our region. What is happening to a lot of our farmland? What is urban sprawl?


Farming is a career that sometimes spans generations. What other careers are like that? Why do you think that is?
For tomorrow, think about the benefits and challenges of running a family farm.
