How many tiles would i need to by if each tile was 2ft by 2ft and the square footage was 69x69

This is the formula you would use to calculate how many tiles you would need.

# of tiles you need = Total square footage ÷ square footage of each tile 

Total square footage: 69x69 = 4761 square feet
Square footage of each tile = 2x2 = 4 square feet

# of tiles you need = 4761 ÷ 4 = 1190.25 

You will need 1190.25 tiles.
