Find the area of rectangular plate having length (21.3 ± 0.2 ) cm and width (9.8 ± 0.1 ).

 

Find the area of rectangular plate having length (21.3 ± 0.2 ) cm and width (9.8 ± 0.1 ). 

Area = ?

 Length = (21.3 ± 0.2 )
 Width = (9.8 ± 0.1)

Here Area = Length × Width

 Area = (21.3 ± 0.2 ) × (9.8 ± 0.1)

 Area = 21.3 ( 9.8 ± 0.1) ± 0.2 (9.8 ± 0.1)

 Area = 208.74 ± 2.13 ± 1.96 + 0.02

 Area = 208.74 + 0.02 ± 2.13 ± 1.96 ▭

(Area = 208.76 ±4.09)
