5*5=25 FOR THE AREA OF THEPHOTO.
THE FRAME IS (5+2X)^2 X BEING THE FRAME WIDTH
THUS THE TOTAL AREA IS (5+2X)^2=50 OR
25+20X+4X^2=50
4X^2+20X+25-50=0
4X^2+20X-25=0 USING THE QUADRATIC EQUATION WE GET
X=(-20+-SQRT[20^2-4*4*-25])/2*4
X=(-20+-SQRT[400+400]/8
X=(-20+-sqrt800)/8
X=(-20+-28.28)/8
X=(-20+28.28)/8
X=8.28/8
X=1.0355 IN. ANSWER. THE WIDTH OF THE FRAME.
