Possible Correct Answer: 10, 23 Answer: Width = 10 feet, Length = 23 feet The perimeter of a room is twice the length plus twice the width. Since x is the width, the length of the room is (3 + 2x). Using this, the equation is: x + x + (3 + 2x) + (3 + 2x) = 66 Solve this equation. First, simplify the left side by combining like terms: 6x + 6 = 66. Subtract 6 from both sides: 6x = 60 Divide both sides by 6: x = 10. So, the width is 10 feet and the length is 23 feet.
