A Norman window has the shape of a rectangle surmounted by a semicircle. Suppose the outer perimeter of such a window must be 600 cm. In this problem you will find the base length x which will maximize the area of such a window. Use calculus to find an exact answer. When the base length is zero, the area of the window will be zero. There is also a limb on how large x can her when x is large enough, the rectangular portion of the window shrinks down to zero height. What is the exact largest value of x when this occurs?

A Norman window has the shape of a rectangle surmounted by a semicircle. Suppose the outer perimeter of such a window must be 600 cm. In this problem you will find the base
length x which will maximize the area of such a window. Use calculus to find an exact answer.
When the base length is zero, the area of the window will be zero. There is also a limit on how large x can be: when a is large enough, the rectangular portion of the window
shrinks down to zero height. What is the exact largest value ofx when this occurs?
largest æ:
cm,
Determine a function A(x) which gives the area of the window in terms of the parameter a (this is the function plotted above):
A(x) =
cm?.
Now find the exact base length x which maximizes this area:
cm.
