Area of frame = Area of Whole Area(photograph+frame) - area of square photograph
125 = X -100
X = 225
Area of whole area = 225
Since the width is uniform and is surrounding a square the outer area of square is also a square. The side of outer frame = S^2 = 225 => S = 15
Outer length - inner length of square = 15-10 = 5
Since the width is on all side. Outer length= inner length+width+width
15=10+w+w
5=2w => w=2.5
Answer is B

IMO B
Area of square = 10^2
Length of outer frame = 10 + 2x
Width of outer frame = 10 + 2x
Area of frame including photograph - Area of square = Area of frame
(10+2x) ^2 - 10^2 = 125
(10+2x-10) (10+2x+10) =125
2x(20+2x)=125
4x^2 + 40x -125=0
4x^2 +50x -10x -125 =0
x= 5/2
Area of square = 10^2
Length of outer frame = 10 + 2x
Width of outer frame = 10 + 2x
Area of frame including photograph - Area of square = Area of frame
(10+2x) ^2 - 10^2 = 125
(10+2x-10) (10+2x+10) =125
2x(20+2x)=125
4x^2 + 40x -125=0
4x^2 +50x -10x -125 =0
x= 5/2
