A grid of square tiles has the same number of rows and columns. If there are s tiles in each row, write an expression for the total number of tiles, and then for the number of tiles NOT on the border (the inner tiles), given s is more than 2.

Question

Accepted Answer

s^2; (s - 2)^2. Total tiles = s × s = s^2. Removing one tile from each of the 4 sides leaves an inner square of side s - 2, so inner tiles = (s - 2)^2.
