Answer: Jeff needs 231 tiles.

Explanation:

Hi, to answer this question, first, we have to calculate the area of the room by multiplying its measures:

Area: 21 x 11 = 231 square feet

If each tile measures 1 ft2 , if we multiply the area by the measure of each tile.

231 x 1 = 231 tiles

Jeff needs 231 tiles.

Feel free to ask for more if needed or if you did not understand something.
