A Norman window has the shape of a rectangle surmounted by a semicircle as in the figure below. If the perimeter of the window is 37 ft, express the area, A, as a function of the width, x, of the window.

Question

How do you do this problem?

Answer 1

Perimeter=w+2h+pi*w.2

area=lw+1/2 PI (w/2)^2
now go to the perimeter equation, and solve for l, then put it in the area equation?

Answer 2

60.1
