I'll assume that the circles are congruent. |dw:1348346022932:dw| if the width is 14 cm then the diameter of each circle is 14cm and the radius is 7cm the length of the rectangle will be 3 diameters of 3 x 14 cm so the Area of the rectangle = 7 x 14 Area of the circles = 3 x (3.14 x 7^2) the difference would be the shaded area. As I don't have a diagram to work off.

first you multiply the are of the rectangle which is 98 then the area of the circle which is 3(3.14x 49) and i got 461.58 then do you subtract them from each other ?? I'm confused
