Draw the description this way:
Rectangle y high and 2x from left to right. In the middle of either length put a point and draw segment to each 'opposite' corner. This will look like two smaller rectangles of x by y with diagonal d.

(An actual picture would be better....)

You will have these equations according to what is given and the description.

Three equations in three unknowns.
Solve for y and 2x.
