A room has a perimeter of 52 ft. The length x is 6 ft greater than the width y. Which shows the correct system and the dimensions of the room? A. 2x + 2y = 52; x + 6 = y + 6; x = 10 ft, y = 16 ft B. 2x + 2y = 52; x + 6 = y; x = 16 ft, y = 10 ft C. x + y = 52; x = y + 6; x = 22 ft, y = 28 ft D. 2x + 2y = 52; x = y + 6; x = 16 ft, y = 10 ft
