Compute the number of vinyl tiles, measuring 28 inches on each side, needed to tile a kitchen measuring 102 ft. by 18 ft.
ratelena [41]

Answer:

338 tiles

Step-by-step explanation:

First, convert the measurements of the kitchen from feet to inches by multiplying each measurement by 12.

102 * 12 = 1224     18 * 12 = 216


Now multiply these answers together.

1224 * 216 = 264,384 square inches


Now find the area of the vinyl tiles.

28 * 28 = 784 square inches


Now find how many 784 square inch tiles are needed to cover a 264,384 square inch kitchen.

264,384 / 784 = 337.224


Since you can't buy part of a tile, round your answer up.

338 tiles
