Question 683823: the area of a square is 169 square centimeters. how long is each side of the square

You can put this solution on YOUR website!
In a square all sides, s, are the same, so instead of a=lw, we can substitute
a = s^2.
...
169 = s^2
Take the square root of each side
sqrt%28s%5E2%29 = +/-sqrt%28169%29
s = +/- 13
However, a side cannot have a negative dimension, so
highlight_green%28s+=+13%29
