"Produce the northern and southern sides towards the east as much as you wish (a side of the transformed rectangle to be. Complete the rectangle and) draw the diagonal passing through its north-eastern corner. (Find the point) where it cuts the transverse side of the (given) square lying inside that rectangle. Leave off the portion of that side lying to the north of that point and make its southern portion the breadth of a rectangle. That will be the rectangle, (required)."²
