Question 833725: The length of a rectangle is 2m more than 3 times its width. If the area is 20m squared, find the dimensions of the rectangle to the nearest hundreth of a metre.
I have tried:
A = l x w
A = (3x + 2) x
I continued trying to solve x despite the fact that I know you can only have one variable when you are trying to fing it and, as expected, I got nowhere. Please help?

You can put this solution on YOUR website!
w is for width
L is for length, using UPPER CASE so we do not confuse with the digit, "one".

L=2%2B3w ; wL=20 .

Maybe those two translated, simultaneous equations are what you need to take an effective path to a solution.
