Question 440519: so there are two squares, one inside the other. the outside one is 10 by 10ft, and you want a tile border around the edges. Each tile in the border is exactly 1 by 1ft. Please help me with an algebric way to calculate the border area, if this was bigger or smaller

You can put this solution on YOUR website!
The inside square is 8' by 8'.
Let b=boarder area
b=10^2-8^2
=100-64
=36 ft^2
