Answer:
The formula for the area of a square with sides of length x is  A = x2  so  
 x2 = 400  is the equation  
 This equation has 2 solutions, namely x = ±√400 = +20 or -20  
 The negative solution does not make sense because a length cannot be less than 0.  
The total length needed to go around the painting is the perimeter of the square, which is  
P = 4*x = 4*20 = 80 inches
