Equation for perimeter:  P = 2*length + 2*width


Let width = x and length = 2x - 5


P:  2(2x-5) + 2*x = 230


Use distributive property


4x - 10 + 2x = 230


Add 10 to both sides of equation and combine like terms.


6x = 240

Divide both sides by 6


x = 40  

substitute 40 for x in equation for length 2x - 5


length = 2(40)- 5
       
       = 80-5

       = 75  
   

So width = 40 and length = 75
