Transcript and Presenter's Notes

Area or Perimeter?

- That is the question!
- An online study guide to help you reviewthe 4th

grade area perimeter objectives.

Area

- The number of square units needed to cover the

region inside a figure. - Area is always measured in square units!

There are 40 squares covering the inside of the

figure.

Area

- To calculate the area of a regular figure use the

formula - Area Length x Width
- Area 9m x 2mArea 18 square meters

Area

- To calculate the area of an irregular figure,

follow these - steps
- Divide the irregular figure into regular

figures. - Look for missing measurements that you will need

to find the area of each new regular figure. - Find the area of every regular figure.
- Add the areas of each regular figure together to

find the total area.

Step 1Divide the irregular figure into regular

figures.

Step 2Look for missing measurements that you

will need to find the area of each new regular

figure.

- This side was 8m
- but because you
- split it to make two
- regular rectangles,
- look carefully at
- every side of the
- figure to see what
- the new measurements
- will be!
- Dont forget the rule,
- opposite sides are
- equal!
- This will help you find the
- missing measurements!

Step 3 Find the area of every regular figure.

- Find the area of rectangle AA L x W
- A 4m x 4m
- A 16 square m

Find the area of rectangle BA L x W A 10m x

4m A 40 square m

Step 4 Add the areas of every regular figure.

- Area of rectangle AA 16 square m

Area of rectangle BA 40 square m

40 square m 16 square m 56 square m

The total area is 56 square m.

Now You Try! Find the area of this figure

Work it out like this

A L x W A 10m x 4m A 40 square m

The length 6m Because 10m 4m 6m

The width 4m Because 10m 6m 4m

A L x W A 10m x 4m A 40 square m

A L x W A 6m x 4m A 24 square m

Did you get the right answer?

Total Area 104 square m

Try another one

Did you get the right answer?

Total area 3,560 square ft.

Perimeter

- The distance around a figure.
- Perimeter is always measured in linear units.

The perimeter of this figure is 51 inches.

Perimeter

- To calculate the perimeter of a regular figure

add the lengths of all the sides! - Perimeter 11m 3m 11m 3m Perimeter 28 m

- Did you get P7m 4m 7m 4m ?
