well a square assumes 4 sides are the same. So you can start by length x height = 81 (the area). So since length and height are equal (b/c it's a square), you can say x squared=81, and solve for x. Then you can get a side.

I'm trying to figure out the rest.

Haha wow it is 3 now I just gotta figure out how to show the work

It would be a 6*12 rectangle. That was stupidly easy.

Draw a square full of little squares. Make sure they're 9*9. Now draw a rectangle that's 6*12 squares. Ta-da.

Ok ok but now give me an equation to show work, I mean I could have gotten the answer by playing the guessing game but I don't know how to turn these words into and equation

217Bimmer 10-05-2012 05:25 PM

x^2=81
x=9
81-9=72
72=(x+y)*(x-y)=x^2-y^2
72=81-y^2
y^2=9
y=3

Your help is greatly appreciated, besides the douchey comment left above

I can also help you with English;) Maybe you should have a little less fun and more time studying.

It makes me sad that college algebra exists. China and India are going to dominate us in 20 years

You really think it is going to take that long?

mbomb3 10-05-2012 08:26 PM

Those type of problems were in my 6th grade math class. I think college algebra is only offered at community colleges. Community colleges...another two years of high school.

ToMuchFun 10-05-2012 08:28 PM

It is a requirement for any degree now
