Question 59263
You've got to get the right picture
width = w
length = w + 3
The 2" border actually adds 4" to the width and 4" to the length.
That's because there's 2" on each side of the photo
{{{(w + 2 + 2)*(w + 3 + 2 + 2) = 108}}}
{{{w + 4)*(w + 7) = 108}}}
{{{w^2 + 11w + 28 = 108}}}
{{{w^2 + 11w - 80 = 0}}}
complete the square
{{{w^2 + 11w + (11/2)^2 = 80 + (11/2)^2}}}
{{{(w + 11/2)^2 = 320/4 + 121/4}}}
take square root of both sides
{{{(w + 11/2)^2 = 441/4}}}
take  the square root of both sides
{{{w + 11/2 = 21/2}}}
{{{w = 10/2}}}
{{{w = 5}}}
{{{w + 3 = 8}}}
so, it's a 5x8 photo
check
{{{(w + 4)*(w + 7) = 108}}}
{{{(5 + 4)*(5 + 7) = 108}}}
{{{9*12 = 108}}}
{{{108 = 108}}}
OK
