a) Find the dimensions of the window so that the maximum amount of light will be allowed into the building that has the window fitted.
b) The window maker did not use the optimum design. Why not?

if anyone has any interesting insights into problems like this, or even this one in particular, i'd love to hear it. It ends up being the optimum height of the rectangle is half the base of the rectangle, which i thought was interesting, but i can't explain why that is instinctively.
Thanks so much for your time
