Question 1891: A rectangular picture measures 8� by 11� before it is framed. The frame has a uniform width, and the total area of the picture and the frame is 238 square inches. What is the width of the frame?

Let the width of the frame be x inches
the picture is 8x11, so its area is 88 square inches.
the picture and frame combined is (8+2x)*(11+2x), which equals an area of 238 square inches.
So lets expand this equation and see what it gives...

hence 2x+25=0 or x-3=0
ignore the first, since this is a negative value. Answer is x=3
cheers
