What is your question, by the way ?   And where is it ?


--------------

For your info: 

    A question is indispensable part of each Math problem.


    Each Math problem must have a question.


    Without a question, the text/(the post) can not be considered as a Math problem.


    Without a question, what you may think is a Math problem, is really a FAKE.


    It is as clear as  2x2 = 4.

-----------------

Even if to forget about the question, wording of the problem is totally unclear.

In this form / (in such a form) it can not be considered as a Math problem, with no any doubts.

In this form, it is good ONLY for re-cycling.

d, the uniform width of the stained glass frame
3, side length of the square mirror
91 sq. in., area of the stained glass frame only

%283%2B2d%29%5E2, the total area of the frame and the mirror
-
3%5E2=9, area of just the mirror
-
highlight_green%28%283%2B2d%29%5E2-9=91%29-------------simplify and solve this for d.
