Question

If the area of a square is 64 inches squared.what is the length of one side

Answer 1

Answer:

8 in

Step-by-step explanation:

Area of a square is given by

A = s^2 where s is the side length

64 in^2 = s^2

Taking the square root of each side

sqrt(64 in^2) = sqrt(s^2)

8 in =s

Answer 2

Answer:

8 in

Step-by-step explanation:

The formula of an area of a square:

$A=s^2$

s - side length

We have the area

$A=64\ in^2$

Substitute:

$s^2=64\to s=\sqrt{64}\\\\s=8\ in$

$\sqrt{64}=8$ because $8^2=64$
