Improved answer:5x2+14x+5 = 5-5x2+14x+5 = 0Solve by completing the square:(x+7)2+5 = 0(x+7)2+5-49 = 0(x+7)2 = 44x+7 = + or - the square root of 44x = -7 + or - the square root of 44
s2, the side length squared = area = 121 s = square root 121 = 11 length total = perimeter = sum of all 4 sides = 4s = 44 cm
44 the sides are 11 and add them up and it is 11x4 or just 44
