I believe the answer is 4.
So here is the solution of the given problem above.
To find the area we are just going to use this formula. A = L x W.
Let x be the width and 2x is the length. Given that the area is 8 square meters. So let us find x first.
Plug in the values:
8 = (2x)(x)
8 = 2x^2 << divide both sides by 2 and we get
4 = x^2
Then square 4 and x^ 2 and we got
2 = x
Therefore, the width of the room is 2 meters and the length 2x is 4 meters. Hope this is the answer that you are looking for.

Step-by-step explanation:
Let N be the number of bacteria as function of the time in hours, and let No be the initial number of bacteria.
<span>
N=No*<span>e^<span>0.061t
</span></span></span><span><span>N/No</span>=2=<span>e^<span>0.061t
</span></span></span><span>0.061t=ln2
</span>t=<span><span>ln2/</span>0.061
t = 0.693/0.061
t = 11.36</span>
Question 1: The area of the square is the product of the two sides. 24 times 24 is 576. Thus, the square is 576 square inches.
Question 2: (Answer is based off info received from comments)
The area of a circle is 
, where r is the radius. The diameter you have given me is 20 inches. The radius is half the diameter; thus, the radius is 10.
They want us to approximate the area. 
is approximately 3.14. If we use this value, we get 314 square inches.
