Can someone help me to answer this correctly, please, and explain it

A student determines the area of a rectangle by measuring the lengths of its sides, using a ruler scribed in centimeters with subdivisions in millimeters. Assume that measurements made with the ruler are accurate to within + or 1mm. The values that the student records are length =19.9cm and width =11.1cm. 1. To 2 decimal places, the calculated value of the area (length width) is 220.89cm2. Based on the significant figure rule for multiplication, how should the area be reported? Area= 2. Including the uncertainty in the measurements, (a) how should the length be reported? 19.9cm+ or - cm (b) how should the width be reported? 11.1cm+ 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 1sig fig and do not report the area beyond the first digit containing the uncertainty. Area=cm2+orcm2 4. Do the methods of reporting the area in 1 and 3 give the same number of significant figures
