Question

The surface area of a typical classroom floor is closest to
A) 100 m2
B) 1 cm2
C) 10 m2
D) 1 m2

Answer 1

I would say C

Answer 2

as an approximation you could assume the classroom is square

so if its area was 1m^2 then it would be a classroom 1m wide by 1m long

if it's area was 10m^2 then it would be sqrt(10)m long by sqrt(10)m wide

do the same for the other 2 options ... which gives you a classroom which is about the size you are used to?

Answer 3

btw C is not a good answer...
