If `L=2.331cm`,`B=2.1cm`, then `L+B=

A

`4.431 cm`

B

`4.43 cm`

C

`4.4 cm`

D

`4 cm`

Text Solution

Verified by Experts

The correct Answer is:
C
Given ,`L = 2.331 cm = 2.3`
(correct up to one decimel places)
since minimum significant figure is `2` and `b = 2.1 cm`
`:. L + B = 2.3+ 2.1 = 4.4 cm`
