Mrs. Fallis needs to convert the units of the tiles from square centimeters to square meters to see if she has enough to cover the counter.
1 cm is equal to 0.01 meters, so the area of each tile is:
3 cm x 3 cm = 9 square cm
9 square cm x 0.0001 square meters/square cm = 0.0009 square meters
Mrs. Fallis has 2000 tiles, so the total area of the tiles is:
2000 tiles x 0.0009 square meters/tile = 1.8 square meters
Since the area of the counter is 2 square meters and the total area of the tiles is 1.8 square meters, Mrs. Fallis does not have enough tiles to cover the counter. She needs to buy more tiles.
Use "converting units"
