Answer:
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.
