We let L be the length and W be the width. We use the equation: L = 3 + 2W. To find the Area, we have: 160 = (W)(3 + 2W) --> 160 = 3W + 2W^2 --> 2W^2 + 3W - 160 = 0 --> W = 8.226, --9.726. Since we have no negative length we use 8.226 as our width. L = 3 + 2(8.226) = 19.452. Length: 19.452 and Width: 8.226.
