"You have been asked to help build a rectangular play area at the new Tracy elementary school. You arrive at the site eager to begin! Much to your surprise, the only things available to work with are two pieces of rope.
Explain how you can use the rope to find the vertices of the rectangle. Include an illustration and a detailed explanation of your solution."
So I've been stuck on this for a while now, and i cant figure it out, I know it has something to do with properties of a parallelogram/rectangle.

The opposite sides have to be the same. That makes it a parallelogram, a good start.
Now the diagonals have to be the same. That makes it a rectangle. 
Of course, bear in mind that the diagonal can't be longer than the longer of the two ropes. (Unless you can join them together)

Explain how you can use a quick picture to find 3 times 2.7.
