    Post Quadratic Formula Question #1

    http://i.imgur.com/1YMipcIh.jpg

    The link above is the question with a picture under it, I am having trouble with these word questions, but I can do regular questions that give you the equation and ask you to get the roots. My problem is reading a word problem and having to create an equation myself, I have always been bad at this...

    All I could come up with was 100m^2 + 30m + 3 = 0

    I know it is probably wrong...

    Any help would be great. Thanks!

    Re: Quadratic Formula Question #1

    The perimeter equals 30m and the area equals 100m2. Can you get two equations from that?

    The answer is 5m by 20m or 10m by 10m, they area equals 100m but do not add up to 30... So, I am still confused.

    From the picture the perimeter is two short lengths+ one long length which is 5+5+20 or 10+10+10

    I don't know??? I'm said I'm not good at coming up with equations. How are you suppose to turn 5+5+20 or 10+10+10 into an equation?
