Square feet refers to area, so you would need to find the area of the room.
Area of a rectangle = length × width
Length = 12 ft
Width = 12 ft
A = l×w
= 12 ft × 12 ft
= 144 sq. ft
Thus, you would need 144 square feet of carpeting.

Answer:<u>
158.7 is the answer</u></h2><h2><u>or it can be</u>
<u>89.7</u></h2>
Step-by-step explanation:
<h2>
<u>69 + Percentage increase =
</u></h2><h2>
<u>69 + (130% × 69) =
</u></h2><h2>
<u>69 + 130% × 69 =
</u></h2><h2>
<u>(1 + 130%) × 69 =
</u></h2><h2>
<u>(100% + 130%) × 69 =
</u></h2><h2>
<u>230% × 69 =
</u></h2><h2>
<u>230 ÷ 100 × 69 =
</u></h2><h2>
<u>230 × 69 ÷ 100 =
</u></h2><h2>
<u>15,870 ÷ 100 =
</u></h2><h2>
<u>158.7</u></h2><h2>

The sum of all five numbers in the list is 25.
According to the question,
The first number on my list of five numbers is 1, and the fifth is 5. The other figures are all one more than their two nearest neighbors' averages.
Let the list of numbers be 1,x,y,z,5.
As each of the other numbers is equal to one more than the average of its two neighbors.
x=(1+y)/2+1
2x=3+y -(1)
Similarly,
y=(x+z)/2+1
2y=x+z+2 -(2)
z=(y+5)/2+1
2z=y+7 -(3)
Multiply equation (2) by 2 and then substitute equations (1) and (3),
4y=3+y+y+7+4
4y=2y+14
2y=14
y=14/2
y=7
From equation (1),
2x=3+7
2x=10
x=5
From equation (3),
2z=7+7
2z=14
z=14/2
z=7
The list is: 1,5,7,7,5
Sum of the numbers of list = 1+5+7+7+5 = 25

First, subtract 40,218-37,842
ex. 40218
-37842
-------------
2,376
Then, round 2,376 to the nearest thousands
2,376 -> 2,000
2,000 is your answer
