Answer:
C
Step-by-step explanation:
a=12,b= 9, c=7
x=-9±√9²-4x12x7/2x12
=-9±√81-336/24
=-9±√-225/24
{x=9+í√225/24 or x=9-í√225/24}
If the area of the square is 9x^+24x+16, then the side length wouldd be the square root of that. That would be 3x+4. The perimeter would be 4 times that so the perimeter is 4(3x+4) = 12x+16
Hope that helped
