The figure above shows the shape of a flowerbed. If arcs WZ and XY are semicircles and WXYZ is a square, what is the area of the flowerbed?
The area = are of the square + area of the whole circle.
(1) The perimeter of square WXYZ is 24 --> side=24/4=6 --> radius=6/2=3. Sufficient.
(2) The diagonal \(WY =6\sqrt{2}\)[/quote] --> side^2+side^2=WY^2=36*2 --> side=6 --> radius=6/2=3. Sufficient.

In order to find the Area of the flowerbed we need EITHER the radius of the semicircle OR side of the square. Either of these values will give the perimeter.
Statement 1
Provides side of the square, Thus Sufficient
Statement 2
Provides side of the square, Thus Sufficient
