Answer:
54.88 in^2
Step-by-step explanation:
Area of a parallelogram is calculated by multiplying height and base
9.8*5.6 = 54.88 in^2
 
        
             
        
        
        
Total distance covered = 5 x 30 = 150 miles
Angle of travel with respect to south pole = 180 - 164°56' = 15°4' 
Let the distance southwards covered be x, then 
cos 15°4' = x/150
Thus, x = 150 cos 15°4' = 144.84
Therefore, the distance covered southwards = 145 miles to the nearest mile.
        
             
        
        
        
The slope is undefined because it is a vertical line on the x axis at 0. Its a straight line going up
