Answer: D. 26 units
Step-by-step explanation: perimeter is the distance around the figure, or all the sides added together. 
With a rectangle it is known that the opposite sides are congruent, or the same, so 8+8+5+5 = 26
 
        
             
        
        
        
Isolate "x" onto one side:
5/3 * (6x+3) < 2x - 7
5(6x+3) < 3(2x-7)
30x + 15 < 6x - 21
24x < -36
x < -1.5
