2. The area of a square is 72 sq in. What is its side length?

defon

Answer:

$6 \sqrt{2}$

if you don't have to simplify it, it is

$\sqrt{72}$

Step-by-step explanation:

the equation for the area of a square is

$a = {s}^{2}$

substitute 72 for a

$72 = {s}^{2}$

take the square root of both sides to cancel out the square on the s

$\sqrt{72} = \sqrt{ {s}^{2} }$

$\sqrt{72} = s$

if you need it simplified, find the perfect square that makes up 72. It is 36.

$\sqrt{36 \times 2} = s$

take the square root of 36

$6 \sqrt{2} = s$
