Question 992478
 he Norman window illustrated below has a semicircular section on top of a rectangle.
 The radius of the semicircle is x.
 The long side of the rectangle is three times the radius of the semicircle.
:
Express the total area of the window, A, as a function of x.
A = {{{1/2}}}{{{pi*x^2}}} + (3x*2x)
A = {{{1/2}}}{{{pi*x^2}}} + {{{6x^2}}}
Express the outer perimeter of the window, P, as a function of x. 
P = {{{pi*x}}} + (2(3x)+2x)
p = {{{pi*x}}} + 8x
