More for the Floor

Solution

Cost: $105.60

Explanation

There are 176 ft². Since each tile is 1 ft², 176 tiles are needed.
Multiply: 176 x $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 x 14 ft = 210 ft².
Find the total area of the two closets: 6 ft x 3 ft = 18 ft², the area of one closet; 4 ft x 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 x $0.60 = $105.60, the cost of the tiles.
