The length of a rectangular classroom is 3 times its width. if the area covered by the classroom is 432 square feet, find the length and width of the classroom

Good morning

w=12 feet

L =3×12=36 feet

Step-by-step explanation:

w×L=432 ⇔ w(3w) = 432 ⇔ 3w² = 432 ⇔ w² = 432÷3 = 144

Then  w = √(144) = 12.

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
