Mary covered her kitchen floor with 10 tiles. The floor measure 6 feet long by 5 feet wide. The tiles are each 3 feet long and w feet wide, what is the missing feet wide?
The area of the floor is 6 ft x 5 ft or 30 square feet. There are 10 tiles so 30/10 would give you 3 square feet for the area for each tile. Area of tile= length x width 3=3w w=1 The width is 1 foot wide.
