Best ResponseYou've already chosen the best response.0Note that you are now showing the area to a precision of hundredths while the linear measurements were only accurate to tenths (precision), the area was obtained from those linear measurments, so how can the area be more precise than the initial base, and height measurements?

Best ResponseYou've already chosen the best response.0The product can not have more significant figures than the smallest number of significant figures as the factors. Your number of significant figures in the height and base were 3, therefore the area can not have more than significant.
