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?
A.m/√n
B.m/√(2n)✓ Correct
C.m/(2√n)
D.√2 m/√n
Explanation
Big square side = √n · s (where s is small side). Diagonal = √n·s·√2 = m. So s = m/(√(2n)).
