Question

The green rectangular-shaped object pictured below is being measured. Its left end is perfectly lined up with $0m$ on the measuring tape.
Which of the following is the best and most precise length of the green, rectangular-shaped object that can be obtained, using the measuring tape?

• A. $2.0m$
• B. $2.4m$
• C. $2.37m$
• D. $2.377m$
• E. $2.5m$

Answer 1

The correct option is B $2.4m$

Least count of the measuring tape $LC=0.1$ m

From figure, the end of the green rectangular object lies between $2.3$ m and $2.4$ m but it is very close to $2.4$ m.

Hence the length of the object is $2.4$ $m$
