Find the area and the perimeter of the shaded regions below. Give your answer as a completely simplified exact value in terms of π (no approximations). The figures below are based on semicircles or quarter circles

Area of a quarter circle of radius 12          =     1/4  pi 12^2

subtract the triangle area:        1/2 b h  =  1/2 12 x 12

perimeter =  hypotenuse of right triangle with legs = 12 and 12             sqrt (122 + 122 )

+  1/4  pi x d              d = diameter = 24
