Question 65571
The question is find the perimeter given the figure 
Here is the rectangle with the figures:

         x
       ------
       2x - 5
--------------------------
-                        -
-                        -    8
-                        -  ------
-                        -  2x - 5
-                        -
--------------------------
The formula for the perimeter of a rectangle is: {{{highlight(P=2L+2W)}}}, where P = perimeter, L = length, and W = width.
{{{L=x/(2x-5)}}} and {{{W=8/(2x-5)}}}
{{{P=2x/(2x-5)+2(8)/(2x-5)}}}
{{{P=2x/(2x-5)+16/(2x-5)}}}
{{{highlight(P=(2x+16)/(2x-5))}}}
Happy Calculating!!!!
