# Square area

Complete the table and then draw each square. Provide exact lengths. Describe any problems you have.

Side Length Area
Square 1 1 unit2
Square 2 2 units2
Square 3 4 units2

Result

a1 =  1 unit
a2 =  1.414 unit
a3 =  2 unit

#### Solution:

$S=a^2 \ \\ a_{1}=\sqrt{ 1 }=1 \ \text{unit}$
$a_{2}=\sqrt{ 2 }=\sqrt{ 2 } \doteq 1.4142 \doteq 1.414 \ \text{unit}$
$a_{3}=\sqrt{ 4 }=2 \ \text{unit}$
