1. The problem statement, all variables and given/known data There is a rectangle in the x-y plane with dimensions H=1, L=2. Find a line or diagonal in the rectangle in which for every point in the shaded area below that line x>y. 2. Relevant equations 3. The attempt at a solution The line has to intersect a point in y=1 in which x>y. This point would be (1,1). But I do not get why.
