Answer:
Length of one side of the region containing small squares is 16 inches.
Step-by-step explanation:
Given:
Area of the chess board = 324 square inches
Border around 64 -squares on board = 1 inch
We need to find the length containing small squares.
Solution:
Let the length of one side of the chess board be 'L'.
Now we know that;
Border around 64 -squares on board = 1 inch
So we can say that;
Length of the side of the chess board = 
Now we know that;
Area of square is equal to square of its side.
framing in equation form we get;

Now taking square root on both side we get;

Now subtracting both side by 2 we get;

Hence Length of one side of the region containing small squares is 16 inches.
