Mr. Santos is carpeting his living room. The room measures 21 feet by 15 feet. The carpeting costs $9 per square foot. How much carpeting will he need (in square feet), and how much will it cost?

Answers

Answer: 315 square feet is needed for carpeting and It costs $2835.

Step-by-step explanation:

Since we have given that

Length of room = 21 feet

Width of room = 15 feet

As we know the formula for "Area of room ":

$Area=Length* Width\n\nArea=12* 15\n\nArea=315\ ft^2$

Hence, 315 square feet is needed for carpeting.

Cost of per square foot of carpeting = $9

Total cost will be

$9* 315\n\n=\$2835$

Hence, it costs $2835.

21*15=315 sqft
315*$9=2,835

How would you do 88.6
x5.01
_____
In traditional algorithm? Offering 54 points

Answers

ok so you mean old school multiplicaton

so what you do is

count how many decimal places the decimal is from the right for top and bottom
add them
88.6 is 1
5.01 is 2
1+2=3
remember to move 3 places to left later
get rid of decimals

now we have
88.6
x5.01

so what you do it
take th rightmost number in the bottom row and multiply it by the top row, 1 number at a time from right to left, if it is over 10, put it over next number to add

886
x501
886

now wedo te next place which is zero so just pt zeroes

   886
x501
886
000

and last part is 5
   443
     886
   x501
886
000
4430

add them

   443
     886
   x501
886
000
4430 +
443886

now remember the 3 decimal places from before?
now put those back, move the decimal place 3 places to the left

443886.0, mvoe 3 to left
443.886

88.6 * 5.01

(88.6)(5.01)

= 443.886

I hope that's help !
