A flower bed is in the shape of a triangle with one side twice the length of the shortest side, and the third side is 30ft more than the length of the shortest side. find the dimensions if the perimeter is 102ft.
 
one would go about this like so
x + 2x + (x-30) = 102

ill let you get an answer, post it and ill see if you got it right
 
Please note that "thirty greater than x" does not translate as "x - 30". Make this correction, and solve.

And you can check your solution yourself, by plugging it back into the original problem (finding the lengths of the three sides), and making sure you get "102" for the perimeter.
