Question

the length and breadth of table measured with a meter scale are 1.31 m and 0.812m. find percentage error in surface area​

Answer 1

Answer:

Given length =1 .31 and breadth =0 .812

There, least count =triangleL =triangle B

=0 .001m

area = L×B=triangle A\A = triangle L\L +triangle B\B

=triangle A\A=0 .001 \1.31+0 .001\0.812 =0 .0019

Perentage error

= triangle A\A ×100%

=0 .2%
