A square sheet is formed by joining n identical square sheets of same size. If the length of the diagonal of the bigger square sheet so formed is m, then what is the side length of a smaller square sheet?

- Am/√n
- Bm/√(2n)
- Cm/√(2n)
- D(√2m)/√n
Explanation
The big square's side is √n times the small side s, so its diagonal m = √2x√nxs, giving s = m/√(2n). (Options B and C are textually identical in the source.) Hence the keyed option is C.
