Question

4.
Four children measure the length of a table which was about 2m. Each of them used different ways to measure it.
(i) Sam measured it with a half metre long thread.
(ii) Gurmeet measured it with a 15 cm scale from her geometry box.
(iii) Reena measured it using her hand span.
(iv) Salim measured it using a 5 m long measuring tape.
Which one of them would get the most accurate length? Give reasons for your answer.

Answer 1

Answer:

The correct answer is option (iv). The most accurate measurement will be done by Saleem as he used a standard instrument to measure the table that is a 5m measuring tape, which made easy for him to measure the table in one go.

Answer 2

Answer:

iv) is the correct answer

because one cannot measure 2m using 0.5m long thread,so (I) Is wrong

while measuring it with 15m scale it is very hard to measure accurately so (ii) is also incorrect

since Reena is a child,the length of her hand will be obviously small so her hand measurement will be not that accurate.

THEREFORE (IV) IS THE CORRECT ANSWER
