Jeff has a job to tile a room 21 ft x 11 ft with 1 ft. square tiles. how many tiles does he need?

Jeff needs 231 tiles.

Step-by-step 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.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
