I'd plug in the options for this question.

Check option A: if the number of meters in AB is 100, then the number of centimeters is 100*100. The square root of 100*100 is 100: 100 = 100.

Answer: A.

10m=1000cm (1m=100cm)
10m=\sqrt{1000} is not=to 10 hence wrong.
and
100m=100*100cm=\sqrt{10000}=100cm.

GMAT questions appear easy when solution is presented but many test takers make mistake during the exam due to time limitation, careless mistakes or not understanding the question properly and hence many seemingly easy questions appear to be at an higher level.

hi

I think it makes sense...

m = √cm

1m = 100cm

100m = 10000cm

100m = √100cm

cheers through the kudos button if this helps 8-)
