Answer:
[tex]\frac{5}{9}[/tex] in
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the side length )
Given A = [tex]\frac{25}{81}[/tex] , then
s² = [tex]\frac{25}{81}[/tex] ( take the square root of both sides )
s = [tex]\sqrt{\frac{25}{81} }[/tex] = [tex]\frac{\sqrt{25} }{\sqrt{81} }[/tex] = [tex]\frac{5}{9}[/tex]
