Question 36897: a rectangular picture is 12 by 16 inches. if a frame of uniform width contains an area of 165 square inches, what is the width of the frame. Answer by checkley71(8403) (Show Source):
You can put this solution on YOUR website! 165=24X+32X+4X~2 24X IS 2*12*x WHERE X IS THE FRAME WIDTH & 32X IS 2*16*X
THE 4 COENERS HAVE AREA OF X~2 THUS THE 4X~2
165=56X+4X~2 or 4x~2+56x-165=0 OR (2X+33)(2X-5)=0 OR x=5/2 OR 2.5 INCH WIDE
