We first calculate the inside area: 6 cm x 11 cm = 66 cm^2. The total area of the frame is: 28 cm^2 + 66 cm^2 = 74 cm^2. We assume that the Length of the Frame is 11 + 2x, where x is the width of the frame area. And the Width of the frame is 6 + 2x. Now we calculate x first: (11 + 2x)(6 + 2x) = 74 --> 66 + 22x + 12x + x^2 = 74 --> x^2 + 34x - 8 = 0 --> X = 0.2337 and -34.2337. We use 0.2337 since there is no negative width. Width = 6 + 2(0.336) = 6.4674 cm.
