minimum area for square is either 9*9= 81 or 15*15=225. 81 is less so 81 sq. inches

each tile has a side length of 9 inches and you'd have a box of nine rows and nine columns of tiles like this

so each end has nine tiles * 9 inches per tile, so that's 81 inches of tile on each side, 4 sides total so you get 81 times 4 is equal to 324 in of tile (perimeter)
