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 (12^{2 }+ 12^{2 })

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