1.	Length and breadth of rectangular field (25.2+-0.5) and (18.6+-0.8).find area of rectangular field within limit of errors. Find percentage errors in area
Answer» ANSWER: Area=l×b A △A = l △l + b △b =( 25.2 0.1 + 16.8 0.1 )=0.00992≈0.01 This is the RELATIVE ERROR. Percentage error =0.01×100=1%

Length and breadth of rectangular field (25.2+-0.5) and (18.6+-0.8).find area of rectangular field within limit of errors. Find percentage errors in area

Answer»

ANSWER:

Area=l×b

△A

△l

△b

25.2

0.1

16.8

0.1

)=0.00992≈0.01

This is the RELATIVE ERROR.

Percentage error =0.01×100=1%
