Question

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

Answer 1

9 meters

Explanation:

Area of a square:

`A=s^2`

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:

`A=s^2\\81=s^2\\s^2=81\\s=√(81)\\s=\pm9`

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