NZ Level 4 Introduction to Area
Lesson

## Measuring Space

Area, is defined as the space within a 2D shape.

All these shapes have the same area as they all contain 5 square units each.   As well as whole unit squares, sometimes shapes might be composed of parts of unit squares.  Take this shape for example. So this shape would have a total of $3$3 whole square units, $1$1 half a square unit and $2$2 quarter square units resulting in a total area of

$3+\frac{1}{2}+\frac{2}{4}=4$3+12+24=4 square units

#### Worked Examples

##### QUESTION 1

Find the area of the shape. 1. $\editable{}$ units2

##### QUESTION 2

If the large square has an area of $1$1 unit2, what areas do the smaller shapes have?

1. $1$1 unit2 $\editable{}$ unit2 $\editable{}$ unit2 $\editable{}$ unit2 $\editable{}$ unit2

##### QUESTION 3

Find the area of the shape. 1. $\editable{}$ units2
