Step 1. Find the product of the base (8.5 cm) and the height (5.4 cm). Post your results.
now for step 2.
Multiply that result by .5 to get the area.
Not the answer you are looking for? Search for more explanations.
Step 3. Round your result to the appropriate significant figures
Note 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?
huh i am lost
The 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. Check out this thread.
In fact watch that movie, and if you have to check out the previous videos.
good luck with your studies.
