Need math help

Hey guys, I really just need help setting this word problem up into numbers and variables, any help would be great

three fiddy

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. Tada.

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.

It is a requirement for any degree now
