What is the square root of 103?

logan13 · Answer

10.14

sand-lock53 · Answer

good! now ignore the 4 in 10.14, and you have the right answer.

phi · Answer

you have to know the area of a square is the length of a side times itself:

s^2 = A

in this case
s^2 = 103
s= sqr(103)

we know (right?)  10*10 is 100, so we would expect s to be close to 10

*C

phi · Answer

yes. as a check,  you can figure out the area if the side is 10.1

10.1 * 10.1 = 102.01
and that is close to 103  (it's not exact because we rounded to only the nearest 10th)
