The area of a square garden is Q square feet and the perimeter is P feet. If Q=2P+48, what is the perimeter of the garden in feet?  Select the correct option:
A) 36 B) 40 C) 44 D) 48 E) 52
Let x be the length of one side of the square garden.   x^2 = 8x + 48   x^2 - 8x - 48 = 0   (x-12)(x+4) = 0   x = 12, -4   P = 4(12) = 48   The answer is 48.
