Question 372455
Picture width = 5 in
picture length = 8 in
Area = 40 in^2
...
uniform width let it be x in
..
total width = 5+2x
total length = 8+2x
..
Total area = (5+2x)(8+2x)
=40+10x+16x+4x^2
=4x^2+26x+40
...
Total area - picture area = area of frame
4x^2+26x+40 -40=114

4x^2+26x-154=0
...
use the quadratic formula to get the roots of the equation
discriminant = 3140
x1= {{{(((-26+sqrt(3140))/(8)))}}}
x1= 3.75
x2={{{(((-26-sqrt(3140))/(8)))}}}
x2=-10.25 ( ignore )
width = 3.75 in
