Answer:
D. Calculate the area under the graph.
Explanation:
The distance made during a particular period of time is calculated as (distance in m) = (velocity in m/s) * (time in s)
You can think of such a calculation as determining the area of a rectangle whose sides are velocity and time period. If you make the time period very very small, the rectangle will become a narrow "bar" - a bar with height determined by the average velocity during that corresponding short period of time. The area is, again, the distance made during that time. Now, you can cover the entire area under the curve using such narrow bars. Their areas adds up, approximately, to the total distance made over the entire span of motion. From this you can already see why the answer D is the correct one.
Going even further, one can make the rectangular bars arbitrarily narrow and cover the area under the curve with more and more of these. In fact, in the limit, this is something called a Riemann sum and leads to the definition of the Riemann integral. Using calculus, the area under a curve (hence the distance in this case) can be calculated precisely, under certain existence criteria. 
 
        
                    
             
        
        
        
Answer:
a) The perimeter of the rectangle is 29.4 centimeters.
b) The uncertainty in its perimeter is 0.8 centimeters. 
Explanation:
a) From Geometry we remember that the perimeter of the rectangle ( ), measured in centimeters, is represented by the following formula:
), measured in centimeters, is represented by the following formula:
 (1)
 (1)
Where:
 - Width, measured in centimeters.
 - Width, measured in centimeters.
 - Length, measured in centimeters.
 - Length, measured in centimeters.
If we know that  and
 and  , then the perimeter of the rectangle is:
, then the perimeter of the rectangle is:


The perimeter of the rectangle is 29.4 centimeters.
b) The uncertainty of the perimeter ( ), measured in centimeters, is estimated by differences. That is:
), measured in centimeters, is estimated by differences. That is:
 (2)
  (2)
Where:
 - Uncertainty in width, measured in centimeters.
 - Uncertainty in width, measured in centimeters.
 - Uncertainty in length, measured in centimeters.
 - Uncertainty in length, measured in centimeters.
If we know that  and
 and  , then the uncertainty in perimeter is:
, then the uncertainty in perimeter is:


The uncertainty in its perimeter is 0.8 centimeters.
