Answer: Choice B) 20*sqrt(2)  ft

-----------------------------------------------------

I'm assuming that the A stands for area. If so, then A = 200 is given to us
Plug this into the formula to get....
d = sqrt(4*A)
d = sqrt(4*200) 
d = sqrt(800)
d = sqrt(400*2)
d = sqrt(400)*sqrt(2)
d = 20*sqrt(2)

saw5 [17]
<span>As of January 8, 2015, the U.S. is $18.1 trillion in debt. (Source: National Priorities Project)

1 Trillion

= 1 Thousand Billion

= 1,000,000,000,000

= 10</span>¹²
<span>
---------------------------

U.S National debt currently stands at:

$ 18.1 x 10</span>¹²
<span>
*<em>What information would be lost?</em> Well firstly the 0's. The 0's put the size of the number into perspective. The word "trillion" would also be taken out of the picture, once again altering the perspective of the number.

Personally I'd prefer to hear "18.1 Trillion Dollars". Sounds more interesting.</span>

To convert the 1.12x into a percentage, multiply 1.12 by 100

This gives you:  112%
