( I realize that I posted this earlier, the one I posted earlier i left part of the problem out and then the Gentlemen attempting to help my never responded)
Consider a window the shape of which is a rectangle of height surmounted a triangle having a height that is 1.5 times the width of the rectangle. If the cross sectional area is A, determine the dimensions of the window which minimize the perimeter.
I think over all area will equal
For the rectangle
Perimeter = 2w+2h
Then i turned the triangle into a right triangle by cutting it in half.
and then to solve for the triangle side we have
I am not sure where to go from here
