### Introduction to rectangles, perimeters, area

What Do We Know About Rectangles ?

- All 4 sides are

- But they

Perimeter- All 4 sides are

**not**equal- But they

**can be equal**which is a**square**

- So a**square**is a**rectangle**

- But a**rectangle can't**be a**square**or is not a square*(Because square sides are all the same and equal , at the mean time at a rectangle only the length and length are the same and the width and width are the same)*

-Perimeter is the space around an object or a shape (going around)

How Do We Get The Perimeter ?

We follow simple steps to find the perimeter :

P= s+s+s+s

eg. A rectangle has the length of 4 and the width of 5. What is the perimeter?

P=4+5+4+5= 18

Area

-Area is the space that is inside a shape or an object

How Do We Get Area ?

We follow a simple step to find area :

A=l(x)w(x)h

eg. A rectangle has the length of 4 , width of 5 , and height of 8. What is the area?

A=4(x)5(x)8

=160

After a brief introduction to what we know, we did some work with what we then learned

#Tiles Is it a square or no ? Area

1 yes 1

2 no 2

3 no 3

4 yes 4

Then for homework we had to do the following :

Side length of square Area of square

1 1

2 4

3 9

4 16

5 25

6 36

7 49

Reminder : The way we find the answers are just like the times table. n by n (nxn)

Dear Jem. Some pictures would add life to a good scribe post. Thanks for scribing

good job jem!! Nice explaination but like Mr. h said,, you can do better by adding life to it ( which is impossible when u look at it differently lol) like by adding picture and colors (:

good job again (:

Good job Jem you explained things very well.

nice job jemmy, but you couldve made the words a little bit bigger.
