Question 502675
width= x
length= 3x+2
Perimeter = 28 inches

x+x+3x+2+3x+2 = 28

8x+4= 28
  -4  -4

8x=24
-- --
8  8

x=3

******* NOW THAT YOU KNOW x......... Substitute**********

width = x = 3 inches
length = 3x+2= 3(3)+2 = 9+2= 11 inches

So the dimensions are 3 inches by 11 inches!

Hope that helped :)
