first subtract the areas 480 - 14*18 = 228 Let x be width of trim trim can be divided into 4 rectangles plus the 4 square corners corner area = x^2 2 rectangles = 14x 2 rectangles = 18x -> 4x^2 +28x +36x = 228 4x^2 +64x-228 = 0 x^2 +16x - 57 = 0 (x+19)(x-3) = 0 **x must be positive** x = 3
make sense ?

Shouldn't it be more since it's all around the T.V?
you are thinking length...it just wants how wide the trim is so its 3in. from edge of screen to edge of TV
the length or perimeter of the trim would be 18+18+14+14+3+3+3+3 = 76 in
