**Reiny**, Friday, December 23, 2011 at 6:51pmI sketched it the following way:

a square joined to the width of the rectangle on the left side

A semi-circle on top with diameter along the length of the rectangle.

A semi-circle at the right side of the rectangle with diameter along the width of the rectangle.

Area of square = 64

area of rectangle = 128

area of small sem-circle = (1/2)π(4^2) = 8π

area of large semi-circle = (1/2)π(8^2) = 32π

total = 64+128+8π+32π = .....
