Question

The floor of a rectangular room will be tiled with square tiles that measure 3 inches on each side. The room is 109 inches long and 103 inches wide. How many tiles, including parts of tiles, are needed to complete the job?

Answer 1

you need to first find the area of the room, then divide it by the area of each individual tile

Answer 2

is it multiple choice?

Answer 3

Choices- and i know it's not A
A. 1,248 tiles
B. 1,247 tiles
C. 1,224 tiles
D. 1,295 tiles

Answer 4

i think B

Answer 5

Since they give you the 2 sides of a rectangle and clearly ask for the measurement's inside, you should find the area.

Side 1 (109) * Side 2 (103) = 11227

Each tile is 3 inches. Find the area of a square which is, side squared OR side * side.
The area of the square tile is 9.

To find how many tiles are needed, do 11227 divided by 9 and you will get 1247.444444

This number rounded is precisely equaled to ?; which is ?

Answer 6

@HonorsStudent look at the first time @UsArmy3947 responded it explains it.

Answer 19

Isnt it A because the part of the tile has to be included? so you would need to round 1247.4444... to 1248

Answer 20

how do you become a moderator in openstudy?

Answer 21

its not a cause you cant round up. from .4 it would have to be 1247.5 but its not..

Answer 22

ok there was a question for that here the link http://openstudy.com/study#/updates/4f667f95e4b0f81dfbb475a2

Answer 23

so it comes down to how well you interact, and the traffic on the site.

Answer 24

You can round up from 4 in this case because you need another tile to fill that .4 spot

Answer 25

yes it does

Answer 26

When it comes to rounding. the rule is, that you cant round up unless its .5 or more. but anything less than .5 cant be rounded up to the next whole number.

Answer 27

thank you

Answer 28

Yes I realize that, but if you are left with an open spot in this kind of a problem, even if it is .1 you can round up because it is necessary to have another tile to fill out the entire room. Rounding down in this case would mean the room is not entirely filled out and there is an open spot

Answer 29

no problem
