Josie has a rug with an area of 18 square feet. she will put the rug on a floor that is covered in 1/3-square-foot tiles. how many tiles will the rug cover?

54 tiles

Step-by-step explanation:

Recall that the area of a square is A = s², and note that the area of each tile is (1/3) ft².  How many tiles will 1 ft² of rug cover?

Divide 1 ft² by (1/3) ft², obtaining 3 tiles per 1 ft² of rug.

Given that there are 18 ft² of rug, how many tiles altogether will this rug cover?  Multiply 18 ft² by (3 tiles) / (1 ft²), obtaining the final result:

18 ft² of rug here will cover 54 of these tiles.
