Can someone help me to answer this, please, and explain it. This is chemistry

Assume that measurements made with the ruler are accurate to within + or - 1 mm. The values that the student records are length =17.9cm and width =16.3cm. 1. To 2 decimal places, the calculated value of the area (length width) is 291.77cm2. Based on the significant figure rule for multiplication, how should the area be reported? Area =cm2 2. Including the uncertainty in the measurements, (a) how should the length be reported? 17.9cm+ or cm (b) how should the width be reported? 16.3cm+ or - cm 3. Use the values from 2. and common sense here. (a) To 2 decimal places, what is the maximum calculated value for the area? (b) To 2 decimal places, what is the minimum calculated value for the area? cm2 (c) Including the uncertainty, how should the area calculated from the recorded length and width be reported? Hint: Use the range from (a) and (b) to determine the + or - uncertainty in the area to 1 sig fig and do not report the area beyond the first digit containing the uncertainty. Area = cm2+ or cm2 4. Do the methods of reporting the area in 1 and 3 give the same number of significant figures? significantly larger value, or which would give essentially the same value.
