Question 413968: if the lenght is 2 more than 4 times the width. the perimeter is 158.
is there something missing, i took it as saying the length is 4 times the width plus 2. is there a formula to break down perimeter backwards?
i came up with 15.4 as width, and 63.6 as lenght,to give me 158 for perimeter, but mainly thru trial and error method, i took a number times 4 then added 2 till i got 158, i know that wasnt the way it supposed to be done, was wondering what the formula and how work should be shown.

You can put this solution on YOUR website! if the lenght is 2 more than 4 times the width. the perimeter is 158.

------------------
L = 4W + 2
Perimeter = 2L + 2W = 158
2(4W+2) + 2W = 158
4W+2 + W = 79
5W = 77
W = 15.4
---------
L = 63.6
----------
P = 2L + 2W is the only "formula" involved
PS It's length, not lenght
