What is the side length, s, of the square? Enter your answer in the box.
A = 81 m2



Sagot :

Answer:

9 meters

Step-by-step explanation:

Area of a square:

[tex]A=s^2[/tex]

There are only 2 variables in this equation, and as A is already given, you can solve for s. Just plug in the given value and go from there:

[tex]A=s^2\\81=s^2\\s^2=81\\s=\sqrt{81}\\s=\pm9[/tex]

You cannot have a negative side length, so the answer here is just 9 meters.
