Answer:
   9.233 ft, 23.233 ft
Step-by-step explanation:
If the shorter leg is x, then the longer leg is x+14 and the Pythagorean theorem tells you ...
   x^2 + (x +14)^2 = 25^2
   2x^2 +28x +196 = 625
   x^2 +14x = 214.5
   x^2 +14x +49 = 263.5
   (x +7)^2 = 263.5
   x = -7 +√263.5 ≈ 9.23268
The two leg lengths are √263.5 ± 7 feet, {9.23 ft, 23.23 ft}.
 
        
                    
             
        
        
        
98-70 is 28 meaning that the range is 28
