Question 768086
An imagined way to begin:

x y plane, rectangle with sides two adjacent sides, from (0,0) to (50000,0) and from (0,0) to (0,1200).  Sketch a segment from (0,0) with slope 1, 346 units in length.  Draw a segment extending from this endpoint to the x-axis.  Now you have an isosceles 45-45-90 triangle.  Hypotenuse is 346 units.  Calculate the length of a leg of this triangle.  How many of these leg legnths are still contained along the x-axis which still hold a rectangular form?
