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 100m^{2}. Can you get two equations from that?

Re: Quadratic Formula Question #1

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.

Re: Quadratic Formula Question #1

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

Re: Quadratic Formula Question #1

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?
