Question

anonymous · Answer

Set up a quadratic.
108 = (x + 5)(x + 2)
Then once you get x, plug it into x and x + 2 to get the dimensions.

so lets put it like this
the length is the width plus 3.
width= w
so L=W+3
and the border is 2 inches wide, so that means that the borders length is L=w+3+2 
so L=W+5
and the width is w=w+2 
get it so far?

and they want you to find the dimensions of the photo.

if 108 is the area of the border then : 108 = L x W (right?)
so then 
108 = ( W+5)(w+2)
can you find what w is? once you find what w is, you can plug it into this: L=W+3 and find out what L is. then you have the dimensions of the photo, just as they asked.
