A = Area
x = Side Parallel to the river.

Which in your context results to:


Area = 1250 yards squared
 
        
        
        
The answer is 0.85 and 85/100 hoped i helped
        
             
        
        
        
If R is the midpoint, then R splits QS into 2 equal sections. Therefore, QR = RS.
8x - 51 = 3x - 6
8x - 3x = -6 + 51
5x = 45
x = 45/5
x = 9
so QR = 8(9) - 51 : 72 - 51 = 21 and RS = 3(9) - 6 = 27 - 6 = 21
so QS = 21 + 21 = 42 <==
