A window frame has the shape of a rectangle surmounted by a semicircle. The perimeter of the frame is constant. Show that, for maximum area, the height of the rectangle is equal to the radius of the semicircle

is this just a rectangle with an arc on top?

yeah..its in the shape of a rectangle with a semicircle on top, so the frame is only the perimeter
