Let us assume the width of the rectangle = x meters Then Length of the rectangle = 2x + 2 Perimeter of the rectangle = 16 meters Then Perimeter = 2 (Length + width) 16 = 2(2x + 2 + x) 16 = 2(3x + 2) 16 = 6x + 4 6x = 16 - 4 6x = 12 x = 2 Then Length of the side of the rectangle = 2x + 2 = (2 * 2) + 2 = 6 I hope that the procedure is clear enough for you to understand and this is the answer that you were looking for.
