There are 176 ft2. Since each tile is 1 ft2, 176 tiles are needed.
Multiply: 176 $0.60 = $105.60, the cost of the tiles
Here is another way to solve the problem.
Find the total area of the room: 15 ft 14 ft = 210 ft2.
Find the total area of the two closets: 6 ft 3 ft = 18 ft2, the area of one closet; 4 ft 4 ft = 16 ft2, the area of the other closet.
The total for both closets is 18 ft2 + 16 ft2, or 34 ft2.
Subtract: 210 ft2 - 34 ft2 = 176 ft2 of floor space, or 176 tiles needed.
Multiply: 176 $0.60 = $105.60, the cost of the tiles.
