A rectangular window is topped with a semicircle. The height of the rectangular part is 1 more than 3 times its width, w meters. Which function represents the total area. A, of the window in terms of the width?

height width OA. A(w) = w(1 + 3w) + (2 ) O B. A(w) = w(1 + 3w) + - * (2 ) 2 OC. A(w) = w(1 + 3w) + 7 ( 20) 2 2 OD. A(w) = w (1 + 3w) + 1( 20)2
