To find the length of a square given the area, we just need to take the square root of the area given. The sqrt of 36 is 6, so each side is 6 inches. :)
Well, a square has four sides. So if you divide four into 36, you get 9. So the answer is 9. But the reason that the answer is nine, is because
So a square has four sides, and every side of that square added together equals 36. And if theres four sides, all you have to do is 36 divided by each side of the square (four sides in total) which gives you 9
