If the length of a rectangular l = 10.5 ...

If the length of a rectangular l = 10.5 cm, breath b = 2.1 cm and minimum possible measurement by scale = 0.1 cm then the area is

A

`22.0cm^(2)`

B

`22.1cm^(2)`

C

`22.05cm^(2)`

D

`22cm^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Area `=1xxb-10.5xx2.1=22.05cm^(2)`.
Since minimum possible measurement by scale is 0.1 cm.
`:.` Area `=22.0cm^(2)`.
