trapezoid area = 1/2(a+b) h
area= 1/2 (120 + 145) 50
area = 25(265) 
= 6,625 yards
 
        
             
        
        
        
60 times larger. 
Hope I helped!!!
        
             
        
        
        
The angle across from A would have to decrease as it should be the same as angle A
        
             
        
        
        
Let’s put these into one fraction each:
Biking: 
= (12*5)/8 miles 
= 60/8 miles
This can be reduced to, 
= 15/2 miles
Swimming:
= (5*2)/3 miles
= 10/3 miles 
Running:
= (6*3)/8 miles
= 18/8 miles 
This can be reduced to,
= 9/4
Now we add all the distances up:
= (15/2) + (10/3) + (9/4)
Now we just can add the numerators and the denominators. We must find the lowest common factor (LCF) for our 3 denominators (2,3,4). Our LCF turns out to be 12. *Remember what we do to the denominator we must do to the numerator. So:
= (15/2) + (10/3) + (9/4)
= [(15*6)/12] + [(10*4)/12] + [(9*3)/12]
= (90/12) + (40/12) + (27/12)
= (157/12)
Therefore Aaron Ran 157/12 miles or 13.08 miles.
Hope this helps!
