Calculate the area, with the appropriate number of significant figures, of a recotangular room that is 14.10 m wide by 15.0 m long.
Is the answer B?
area = L x W = 15.0 x 14.1 = 211.5 m^2 but the answer is not B.
You can have three significant figures (because of the 15.0). I would round that 211.5 to 212 m^2.
