Question

3. Four children measure the length of a table which was about 2m. Each of them used different ways to measure it.
a) Sam measured it with half a metre-long thread.
b) Gurmeet measured it with a 15cm scale from her geometry box.
c) Reena measured it using her hand span.
d) Salim measured it using a 5m long measuring tape.
Which one of them would get the most accurate length? Give reason for your answer.

Answer 1

Answer:

Salim would get the most accurate measure , because

he can measure the whole length in one go while other have to repeat again and again. Also his scale would have metre and centimeter marking whereas Reena and Sam don't have perfect measurement instrument .
