A Norman window has the shape of a rectangle surmounted by a semicircle. If the perimeter of the window is 51.4 ft. give the area A of the window in square feet when the width is 9.9 ft. Give the answer to two decimal places.

9.9  + 1/2 (9.9)pi +2 h = 51.4

h = 12.97 ft  (of the rectangular area)

 

Area =   9.9 * 12.97     +  1/2 (9.9/2)^2 pi = 166.93 ft2
