Question

Emma is installing a new tile floor. Each tile measures 12 inches by 12 inches. The room in which she is installing the tiles measures 14 feet by 10 feet. If each tile costs $1.25, how much will it cost Emma to complete her project?

Answer 1

So basically each of the tile sides measure one foot, since one foot = 12 inches.
We will call one of the tiles a unit.
And since the room is 14 feet by 10 feet, we can multiply the two dimensions together to see how many units fit into the room.
14 * 10 = 140
And so now we know that we need 140 tiles.
And since each tile costs $1.25, we can multiply that by 140 to get the total cost.
1.25 * 140 = $175

So it will cost Emma $175 to complete her project.

Answer 2

we know that 1 foot =12 inches so area of 1 tile is 1 ft square
total area of room =14*10=140 ft square
total tiles required= 140/1=140 tiles
cost of 1 tile = 1.25$
cost of 140 tiles= 1.25 *140=175$
