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.

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

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

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

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.
