My boss asked me to create a 2 acre square. Is there an easy way to do this? I calculated the number of square meters in an acre, took the square root of that and drew two lines at right angles using Direction/distance (started line then did rt click to access Direction/Distance tool). I then used the rectangle tool in Advanced editing (using the shift key to draw a square) and snapped to the lines I created. This worked but theres gotta be a better way to create a square of a given size.

You could alternately create a graphic square and in the properties enter the appropriate length and width. If needed then convert that to a shapefile. For one that is rather clumsy compared to the prior but for many copy and pastes of it it might be okay.
