The area of square A is 25. The area of square B is 81. What's the length difference between the sides of square A and B?
The area of a square is calculated as length * width. Because all a square has all sides equal then we can say that given a side S, the area is S*S.
For square A of sides A, the area is A*A=25 or A^2=25.
Solving for A we know that A=
