There are 176 ft^{2}. Since each tile is 1 ft^{2}, 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 ft^{2}.

Find the total area of the two closets: 6 ft 3 ft = 18 ft^{2}, the area of one closet; 4 ft 4 ft = 16 ft^{2}, the area of the other closet.
The total for both closets is 18 ft^{2} + 16 ft^{2}, or 34 ft^{2}.

Subtract: 210 ft^{2} - 34 ft^{2} = 176 ft^{2} of floor space, or 176 tiles needed.

Multiply: 176 $0.60 = $105.60, the cost of the tiles.
