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

Correct answer:

a₁ =  1 unit
a₂ =  1.4142 unit
a₃ =  2 unit

Step-by-step explanation:

$$\begin{gathered} S=a^2 \\ {a}_1=\sqrt{1}=1\text{ unit} \end{gathered}$$

$a_2=\sqrt{2}=1.4142\text{ unit}$

$a_3=\sqrt{4}=2\text{ unit}$
