The sum of length and width is half the perimeter, 160 yd. The length is the average of the sum and difference of dimensions:
.. (160 +20)/2 = 90
Then the width is 160 -90 = 70
The rectangular field is 70 yd by 90 yd.
        
             
        
        
        
The answer is square root of 6.909877
