Nika is selecting floor tiles for her room in her family's new house. No tiles will be put down in the closets. Each tile is 1 foot square and costs $0.60. All the intersecting sides of the tiles meet at right angles.
How much will the tiles cost if there are no tiles left over?
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.
