  • A 6.00cm2
  • B 6.10cm2
  • C 6cmv
  • D 6.09cm2
  • E 4.00cm2
Correct Answer: Option B
Explanation:
Area of the paper = area of square = L x B or S2
where s = S x k
Area of the paper = (2.524)2
area of the diagram = (0.524)2
area not covered = (2.524)2 - (0.524)2
= 6.370576 - 0.274576
= 6.096
= 6.10cm2 (2 s.f)
