Mark and Juanita want to tile their kitchen floor. If the kitchen floor is shaped like a rectangle and measures 11 feet × 14 feet, how many square tiles will they need to cover the floor is each square tile measures 4 inches × 4 inches?
Convert feet to inches, then divide.
(11*12*14*12)/(4*4) = ?
Let us say that the tile is 4x4
it is best to convert the units of the area from "feet" to "inches" to align it with the unit of the tiles (because that is what's being asked))
The conversion will go like this:
since 1 feet is equivalent to 12 inches
we must multiply
11ft x 12 = 132 inches
14ft x 12 = 168 inches
we will now divide it by the size of the tile
132 inches/4 inches = 33
168 inches/4 inches = 42
Now multiply the two values
33 x 42 = 1386 tiles that has the size of 4 square inches each.
Answer: 1386 tiles
